well nothing is really open, i believe they opened horseshoe bowl for hike to acess only, no clue when they plan on running the t-bar.
i would say check out freeway, i think they are going to leave the dew tour course up for a little while, i could be wrong on that though.
really i would say check out key if you want rails, they are opening fredas, and I-70 in A51 on friday i believe, so that gives them even more options in their already sick rail set up.
if you want to ski jumps all day breck is the place to go.
