Takesabout a month to plan a good ski trip because you definatly want accomidations and you dont want to be looking for them 3 days before your trip oras you arrive, it just will not work that way. Make sure your buddies wont flake out on you because road trips suck ass on your own. and be sure of the route you take dont get lost. It took us canadians some serious figurin' to navigate your Interstates but, worked out in the end.
My favorite trip was last season road trip from Calgary ab to Keystone and Breck. It was a long fucking drive but we did it in something like 21 hours. parks were sick, thats all we went for. except after taking a detour thru Loveland pass I think Id LOVE to ride the BC there. this summer was the first time some friends and I drove to Whistler rather than flying. granted its longer but we felt so much more organized driving then trying to make airports on time, and getting picked up by bus n shit. and once we were there we had a vehicle in Whistler, which isn't all that necessary if you liv in the village, but we were aways away. Anyways, any ski trip ive ever been on has been completely sucessful with lots of good planning. So yah, start planning, because plannins the shit.
