Less prone to explosions, bird collisions, and painful butt-burns, the segway has edged out the jetpack as the official ride of the 23rd century. Practice on these leisurely chariots of fire with today's Groupon: for $25, you get a one-hour Ride It segway tour from SegCity departing from downtown San Antonio (a $50 value).

Part local gurus and part segway soothsayers, SegCity guides ensure safe, fun rides on the newest segways. During a one-hour Ride It tour, these masters of gyroscopic go-how will conduct a training and safety brief before leading two-wheeled wanderers to open spaces, where they can get a feel for their mechanical steeds, riding as they please for the remainder of the session. On-the-go octets can select destinations to create the cruise of their dreams, passing by the Alamo and other historical sites, perfecting figure-nines in wide-open spaces, or showing skateboarders how an ollie is really done. Cast off at 12 p.m. or 7 p.m. daily.
