Spot the Deadhead porn guy in the first "legit" taping section authorized by the Band... as much a way to stuff all the annoying tapers in one area so they weren't "shhhhing" everyone that wanted to scream "Play Dark Star" every two minutes, especially on the East coast.
I used to be heavily into taping shows... until I came to my senses and realized how much more fun it was to "be here now" in the moment, not the recording of the moment.
Of course now, all the smart bands make and sell their own live recordings of shows these days so the impetus to sneak in mics and decks etc is a lot less.
