We wound up getting tix last Sunday on vivid, as secure a ticketing site as stubhub, ie tickets are guaranteed. Paid less than $150. Worth every penny. The Friday crowd was 20's to 70's and exactly what you'd expect. A very friendly and communal atmosphere. The city was very gracious, the venue outstanding. So glad we went, it's a memory that will stay with me forever. They are doing these shows right, they are just being the dead, not some nostalgic tribute. No special guest walk ons, no photo montages, simply up there playing the songs as a cohesive unit. No one is trying to put their own stamp on their performance, they are all doing it Dead-style.
