I plan on buying the Keystone pass...and maybe one packed of copper 4. I had planned on not getting anything until Bruiza mentioned it and then I saw that the mountains are opening like next week..
Arapahoe: Small mountain with not a lot of trails, however that place rides BIG. If you are highly skilled you can get yourself killed there with all the chutes..lol.
Keystone: Family style with some good terrain..nothing that is Great, but everything is good. I like some of their tree stuff and they have a good park.
Breck: I didnt like it...everytime I went it was fucking windy
Vail: Ummm yeah....didnt like it. Maybe it was because the girl I went with cried in the second run, then told me I wasnt snowboarding with her on the 3rd, pouted, got a head ache and then wanted to go home.

I made 1 more run and then we left..

WP: Great for skiing...not so great for boarding.
Copper: Balla park, great rails, big kickers and some fun tree stuff...
thats my take on the mountains
