Cheyenne is about to get a whole lot crazier. The "Nitro Circus" action sports tour is coming to the Big Country Speedway on Sunday, August 27th.

The event features high-flying exhibitions from some of the biggest names in freestyle motocross, bmx, basejumping, scooters, skateboarding and trick-riding.

Led by extreme sports legend Travis Pastrana, Nitro Circus began as a television series in 2006. The brand has since released a series of succesful DVDs and a full length movie.

In 2010, the Nitro Circus Tour was launched and has played to sold out arenas and stadiums all over the world. August marks the first time the event has ever come to Wyoming.

An online presale is underway for the Cheyenne. Tickets will go onsale to the general public next week, via
