Two days of dudes on skates crashing down a giant ice hill riddled with obstacles. More than 100,000 amped-up spectators. Followed by an after-party with DJs in a warming tent. All happening in the shadow of the Cathedral of St. Paul. Aww, yeah! (Pay $5 for access to the Crash Zone, where alcohol is served). Noon-8:30PM Friday, 4:30PM-2AM Saturday. Free. —Heidi Raschke
