Breckenridge: Honestly.....I don't even know. I will say that no one bats an eye...at anything really. Dubs every day, every invert imaginable, every swap, press, butter, tap you can think of, and even better, nasty tranny finding and creativity; maybe not quite as much creativity as a place like Key, but then again, Key's setup is far less traditional and really caters to experimentation and creativity.
The "average" park skier at Breck would probably be the best skier at most resorts east of the Mississippi. But, there's so many kids here who are also just learning and progressing. Huuuuge disparity between the best and worst. I will say that on an average sunny, warm day in the middle of the week, you don't see many straight airs or too many people knuckling. Pretty much everyone seriously lapping Park Lane is at least decent and comfortable spinning jumps roughly 30ft.
