Move over, Granny! Octane Raceway has been letting us fuel our fantasy of the Indy 500 since 2003. This revved-up, third-of-a-mile race track is the only full-time indoor/outdoor track in the country, and on almost every single day of the year, its European electric race karts offer a truly exhilarating experience with zero eco-threatening emissions. Drivers can crank things up to 45 miles per hour, then throw back a brewski at the Octane bar (where staff keeps a breathalyzer handy for anyone keen on getting faced). You might even bump into a racing star there because Octane is home of the Indoor World Kart Championship and has hosted NASCAR stars like Kenny Wallace, Kyle Busch, and Carl Edwards. What are you waiting for? Slip on a helmet and get yourself strapped into an Octane kart.
