Sometimes I carry my Nikon and challenge myself to capture random snaps of skiers at resorts, usually Squaw Valley. Unless a name is noted, the photos are of people I don't know. If you don't want your photo taken, then don't ski or ride so well. Don't wear a colorful outfit. Don't ski under the chair. Don't look like you're having fun. And certainly don't wear red, white and blue underwear.
