Biosphere 2

In 1984, Space Biospheres Ventures purchased a few unassuming acres north of Tucson in the shadow the Santa Catalina Mountains. There, the company expanded its sci-fi-sounding activities-the development of space-colonization technology-and built what would evolve into Biosphere 2. Designed to re-create Earth's ecosystems, the gigantic glass enclosure (some 7.2 million cubic feet and 91 feet tall in some parts) is famous for housing biospherians in the 1990s. The researchers lived completely sealed inside for extended periods, giving scientists groundbreaking data on human survivability and interaction with particular bionetworks.

The University of Arizona purchased the 40-acre Biosphere 2 campus in 2011, maintaining it as a hub of serious research while expanding its mission to encompass interactive educational outreach. Each year, thousands pass through the on-site labs and classrooms as well as stroll the Biosphere 2 interior to view films, experience multimedia exhibits, or embark on guided tours. Tours venture into the actual ecosystems, allowing earthlings to note a coral reef's biodiversity, smell fresh precipitation in the rain forest, and savor the softness of savannah grassland underfoot until the resident grumpy old man yells at you to get the heck off his lawn. Before their dramatic conclusion at a million-gallon ocean tank and its living coral reef, tours delve into the basement to explore the technosphere, where visitors can witness the deep inhales and exhales of the sphere's respiratory system. Surrounded by natural desert preserve, the facility sits at an elevation of 4,000 feet, and is heated and cooled inside based on different climates; visitors may experience a variety of heat and humidity conditions on the under-the-glass tour.

Spacious Suites on Historic WWII Air Base in the Heart of Scottsdale

Between 1942 and 1945, young WWII pilots took off and landed more than 600,000 times on the runways of the Thunderbird II Air Base, situated in the desert outside of Phoenix. Today, jetsetters of a different kind frequent the historic base, which has been repurposed as the Scottsdale Municipal Airport. The base also contains the Scottsdale Thunderbird Suites, a four-story, tawny stucco hotel. Soaring ceilings and thick oriental rugs welcome visitors at the grand entrance area, and there are nods to the property's aviation history throughout the hotel.

Considering its proximity to the runway, each of the hotel's standard suites is rather quiet. That's because each room has been soundproofed with thick concrete walls to reduce the sound of engines and the cries of babies that want their pilot's license 16 years ahead of schedule. All of the spacious suites include a living room and separate bedroom, as well as new, cushy couches and chairs to lend the room homey feel.

Before heading off to bed, stop by the lounge next to the Silver Wings Restaurant to grab a nightcap and browse the hotel's WWII aviation memorabilia. Among the relics are photographs of pilots and a table crafted from an aircraft rotary-cylinder-engine top. In the morning, guests can fill up on eggs, bacon, pastries, and steaming coffee at the complimentary hot breakfast buffet.

Scottsdale, Arizona: High-End Shopping in the "The West's Most Western Town"

Situated slightly northeast of Phoenix in the Sonoran Desert, Scottsdale was once a vast ranch lands lined with citrus farms and cowboy settlements, earning it the nickname of "The West's Most Western Town." Today, the lush desert oasis is studded with glittering outdoor fountains, emerald-green golf courses, and an active nightlife scene.

For many vacationers, "sightseeing" in Scottsdale translates to "window-shopping." A few steps from the hotel, wander past palm trees to find designer stores such as Cartier and Anthropologie. A few minutes away is the charming and quaint Old Town Scottsdale, where brick buildings offer a glimpse into how the town earned its "Most Western" moniker. Stroll down its winding streets to find art galleries, a mammoth used bookstore, and public sculptures on nearly every corner.

KU Studios

Carol Sottosanti inherited her love of hitting high notes and cutting rugs from her father, an opera singer who inspired her to pursue a degree in vocal performance from the University of Arizona. Naturally, Carol wanted her children to also experience the beauty and exhilaration of performing on stage, but she couldn't find a program that would grant her kids the proper exposure and practice they needed. Teaming up with other moms in the community, Carol organized a few small shows starring the neighborhood's charismatic children, and subsequently, Kids Unlimited was born. Since its inception in 1986, KU Studios still produces shows regularly, preparing their young performers with various classes in vocal performance, dance, and acting. Aspiring triple threats can dive into a wide variety of camps designed to hone singing and dancing skills, while promoting awareness of important topics such as bullying or the proliferation of mimes in Tucson. KU's outstanding performers earn their way into small-group ensembles that perform regularly throughout the community.

Drum & Drummer School of Percussion

Drum & Drummer instructor Erik Truelove knows how to improvise. When the country-rocker and four-time winner of the National Association of Music Merchants' World's Most Accurate Drummer title found himself at a TV gig with no cymbals, he simply pulled the license plates off his car and attached them to his kit, he reported to the Tucson Citizen in 2009. This spirit of flexibility and quick thinking is something he passes along to his students in both group and private lessons. Other instructors-all working musicians-join in that goal backed by expertise in hand drumming, R&B grooves, jazz improvisation, and competitive marching percussion.

To mark progress and keep motivation levels kicking, the school uses a program of Truelove's own devising. Modeled on karate's belt system, sets of colored drumsticks provide a vivid reminder of the skills students have conquered. To advance in rank, they must master their level's set of grooves, fills, and concepts, then perform a predetermined song at the school's performance center. Class sizes are typically capped at 10 students to ensure lots of one-on-one assistance and keep the cats from constantly calling the cops with noise complaints.

Natural Way Wellness Spa

While taking a walk, it's not unusual for residents of Tucson to see others out for a stroll, although it might be unusual to see someone stooping to collect leaves from a low-lying plant. But that's exactly what staff members at Natural Way Wellness Spa do to create their seasonal herbal wraps and infusions. They select their local gatherings based on their "wide working knowledge of herbology," says the owner, who supplements her own herbal findings with trips to local herb stores and enchanted forests.

"Tucson [is] such a wonderful community that cares about sustainable foods, that cares about [being green]," the owner says. "Our mission, really, is to bring affordable, safe, and natural services to Tucson." Massage therapists and aestheticians employ organic American-made products to cleanse complexions or detoxify bodies during wraps. Treatments are outlined on a whimsical chalkboard menu, which presides over the spa's comfortable atmosphere with ceilings of exposed wooden beams and pastel walls.
