Motorcycles, like supermans and the Mona Lisa, are thrilling to watch when they are airborne. Keep your eyes on the sky with today's Groupon: for $10, you get two tickets to round two of Stunt Wars at the Central Florida Race Complex in Orlando on June 12, from 12 p.m. to 7 p.m. (a $20 value). Children age 8 and younger are admitted for free.

Stunt Wars pits stunt specialists against each other in extreme riding events. Motor mavens such as Brian Bubash and Jesse Toler, two winners of the previous round of Stunt Wars, will showcase their stunt-jumping and wheel-balancing prowess as they compete in individual freestyle, long-endo, stunt-cross, and penny-farthing events. Alongside the high-stakes tournaments, a host of heart-pumping entertainment takes place, including extreme car-drifting shows, a go-kart racing track (not included with this Groupon), and a giant-sloth rodeo. An array of motorcycle and extreme-sports vendors will be peddling their bikes and accessories, and numerous food vendors will be on hand to ease appetites.
