When you watched Jeret “Speedy” Peterson pull off his amazing “hurricane” during the men’s Olympic freestyle aerials on TV, you could hardly tell the wintry setting was a manmade illusion. Brad Suey, a 45-year-old freestyle veteran from Saco, Maine, managed to create a world-class venue on a mountain that had no snow. After a month building and maintaining the Olympic site at Cypress Mountain near Vancouver, British Columbia, he traveled directly to Schweitzer Mountain Resort to create the stage for Yoke’s Outrageous Air Show tonight and Saturday.
