Ziplines originally were invented for just two functions: sneaking hamburgers over the Berlin Wall and zazzing up presidential entrances to State of the Union addresses. Discover function three and beyond with today's Groupon: for $20, you get five Friday-night open-gym visits at Hartland Gymnastics in Howell, including moonwalk, zipline, trampolines, a foam pit, and more (a $40 value). Open gym is held Friday nights 7:30 p.m.–9:00 p.m.
During open gyms at Hartland Gymnastics, tumblers fling themselves into the foam pit's plush cavern, spring onto trampolines, and flip potential to kinetic on high-energy play-activity equipment. The moonwalk's bouncy surface recreates lunar landings with gravity-defying leaps and rocks made entirely of swiss cheese. A gym instructor remains on-site during gym romps, sharing chaperone duties with parents of kids aged four or younger. No gymnastics experience is necessary for any of the activities, from taking on the professional trampoline to imitating Tarzan's regional ape dialect on the zipline. According to open gym rules, tumblers should be dressed in gym clothes or leotards, rather than street clothes, jeans, or three-piece suits.
