Tricks on skis not limited to the slopes
By Aidan Lewis, BBC News
Slopestyle skiers made a successful debut at the Winter Olympics in Sochi, eliciting gasps with their stunts and jumps. Many miles away in northern parts of the U.S., a growing number of skiers use city settings to perform and film similar tricks.
They scope out urban landscapes to find rails to skid down and walls to slam their skis against. They wait for schools and libraries to close, sometimes emerging only under cover of darkness. They play cat and mouse with the police.
The skiers say that cities allow them to be more creative, and offer greater variety than resorts.
