There is a surprising number of tickets for the 9/18 show on Stubhub at face price. My concert buddy can't make this show and my wife doesn't want to do two nights in a row...the three of us and another friend are all going on 9/19 but part of me REALLY wants to go to 9/18 as well. I can't decide if it's worth braving Red Rocks by myself for the first night.
