do you have to go to copper? Breck's park is ill nasty, and will be heeps more fun than copper. Dunno if presidents day weekend will mean + crowd, it was pretty crazy (at breck) this weekend.
there was some snow today (check the snow reports for how much) so keystone might be fun...their jumps have some strage uber pop on them right now, so if you're looking to ski park, i highly recomend park lane at Breck.
