Keystone - hike to North Bowl is good and in good shape lots to choose from here, trees on the skiers left side of the bowl are good or do the 45 minute hike to the top for the biggest vert. Do yourself a favor and skip South Bowl.
Copper - Tucker Mountain is the good hike to here but is not open and on MLK weekend did not look close to being ready. So pray for snow!!!
Vail - I've only been there about 4 times and don't know any good hike tos. Let me know if you find any. I do know a good traverse here, if you are at the top of the Game Creek bowl on the far west side of the mountain, head towards Sun down bowl, but keep traversing, there are good tracks to follow, basically follow them as far as you can and you'll be right at the western boundary of Vail, nice mellow turns in powder up top, then through some nice aspen glades. Just did that run Saturday, can you say Epic?
Hope you have a blast and pray for snow!!!!
Well I wonder where that skier's bound. Is there some run, somewhere, someway out there that I've not found?
