The first GD show I ever went to I thought was one of the most boring gigs I'd ever seen (Alpine Valley '81). It wasn't until after the show and someone said "see you in Boulder" which I took to understand was where the next show would be. You could have knocked me over with a feather. People were going to travel 900 miles to see this band? That's when I knew I had to dig deeper into this, as there was obviously something I was missing. It was another year before I saw them again, and that was one of the best shows for me (Austin '82) followed by 4 more in the next week. It was 6 months before I saw them again (Vegas '83) and by that time I'd familiarized myself with pretty much all their recorded work. It wasn't until '83 that I started seeing like 4 or 5 consecutive shows, and one would really be a standout, so the others wouldn't be quite on that level. That seems normal, like so many things in life. Yes, it was always better being at a Dead show then just about anywhere else, but they varied and it was noticeable. Matter of fact I'd say I saw the best show followed by what i'd say was the worst, imho.
Now I've not seen nearly as many Furthur shows as many here, but I've yet to see a bad one
