Organizers will truck in 40 tons of faux snow for the ACG Indoor competition, creating quite a climate contrast in the land of surf and sunshine. Snowboarders will compete for $75,000 in prize money and a Mitsubishi Montero.

The first-of-its-kind event is sponsored by Nike and Sega Dreamcast. “We knew that having the world’s best riders on the ramp meant that we also had to have the world’s best entertainment on stage,” a Nike spokesman said.

Eminem, just about the hottest thing around on the strength of The Marshall Mathers LP, wraps up duties on the Up In Smoke tour on August 21. Kottonmouth Kings will squeeze the snowboarder fest into its current tour of clubs and festivals.
