Normally I goto a bar, and am quite shattered after a day on the slopes. Have a few jugs of beer, a few jagermeisters, and then hit the hot tub at the chalet.
Most of the time after a day of snowboarding we either hit a club and have some fun or we will go out for dinner and then come back to the cabin and relax either in the pool or the hot tub. We are not that wild of a bunch really!
Music... Lots and lots of live music. On the best nights, it's a blues club. Otherwise it's usually an alt. rock or punk band. Last really good night out was to see Art Brut in Brooklyn, New York. Great show with two other bands.
