Though it prohibits us from bench-pressing cars, gravity is the best thing for getting water out of the sky and the only thing keeping football stadiums from floating away. Escape its omnipresence with today's Groupon: for $4, you get one sky-ride ticket at Mt. Lemmon Ski Valley in the Santa Catalina Mountains.

Offering scenic views of Tucson and the surrounding area, the Mt. Lemmon Ski Valley sky ride (a $9 value for adults and a $5 value for children) allows lounging adventurers to kick back and catch a bird’s-eye view of nature’s bounty without lassoing an albatross. Each sky ride to the summit takes approximately 30 minutes and covers approximately one mile. Departing from an 8,200-foot base, sky riders will climb nearly 1,000 feet into the clouds while soaking in views of the Reef of Rocks, San Pedro Valley, and the mountains of Globe and Phoenix in the distance. Along the way, scan the surroundings for golden eagles, wild turkeys, and more than 200 species of birds, as well as black bears, mountain lions, white-tailed deer, and dodos.

Veering off a mountain road ramp in a minivan provides striking aerial views, but the experience is over all too quickly, and deploying airbags scare off the surrounding wildlife. Instead, peruse nature’s backyard in a more convenient manner with a sky ride at Mt. Lemmon Ski Valley. Purchase extra Groupons and show family members and pizza-delivery guys that the planet is perfectly flat.
