My Wife and I are driving to from Winter Park to Snowmass for the show Sunday.  I was checking the Snowmass website and noticed their twitter was following a concert by Vampire Weekend tonight. I don't know squat about Twitter, so maybe kcortez is all over this, but I would expect some twitter photos of GPN from this same source.

This is an outdoor show, high in the mid 40s, so no jammies or skimpy dresses at Snowmass! I don't know what to expect for an audience--Mostly disinterested and tired skiers? Aspen is a pain to get from Denver, so I am curious about the turnout. I'm told it's some kind of band shell stage, no seating.

Being from Vermont, are GPN likely to hit the slopes before the show?
