I've been thinking about this thread since it was started yesterday, and for me, the day I retire from stealth taping is the day I retire completely. I suppose maybe if I lived somewhere else, that wouldn't be the case, but i have no loyality to most of the venues I frequent where some just assume charge you for the privilege and I have no desire to try and jump through some of the hoops my fellow open tapers in the area have to deal with. Everything I tape is stealth, the stuff i've posted on LMA, and the times i've plugged into the board have been with artist consent, but not with venue consent. I can't say i've ever felt guilty about it.
Although the things other things people have mentioned annoy me, i like doing it and it keeps me focused on the show. I didn't tape 2 of the 3 Pearl Jam shows I saw last year since they release official boards and it felt completely weird not taping and it actually affected my enjoyment of the shows in a negative way. I also like the challenge of making a good recording under these circumstances.
Anyway, just my .02.
