Claim to Fame: Every bartender has a signature beverage, but Petersen's concoction, lovingly known as the Flaming Asshole, takes sport-drinking to an embarrassing new low. Once a celebrity bartender of sorts at La Cocina (he got canned), where the drink became famous, Petersen now pours at the Steak Pit, a venerable—if relatively tame—eatery known for its top-notch…salad bar.

"She was well endowed rasps Petersen. "She was trying to impress somebody, and it worked—she ended up leaving with him.
PRINCE AMONG MEN: Like everyone else in Aspen, Petersen passes the winter skiing powder and binge-drinking. The difference is that he does it all on the clock: By day he guides for the cat-skiing operation Aspen Powder Tours, tallying 15,000 vert per session. Later, at the Steak Pit, he slams five or six beers.
ON AGING GRACEFULLY: "It's alright, says Petersen with a grin. "You're only as old as the last girl you… (Yeah, yeah, Bert. We get it.)
