Some of the best raves of the late 90s and early 2000s were at The State Palace Theater in New Orleans.. At the last party thrown there, I was invited to play first on the main stage, biggest soundsystem and crowd I ever played for, all my friends there to support.. Set goes great, we all hug and celebrate and and start tripping, and have a great time..
At about 4AM I go to get something in my record bag that I left on the stage by the decks.. someone stole it. It also had my car keys in it, among other things..
My buddy had to drive me 3+ hours away to get my spare keys, and hours back, and hours back home again, it was two days after the party before I finally settled in at home, without most of my keys and my stuff.
I had a friend who recorded and took pictures during my set, but in a different incident at the party, he dropped the camera in a literal hole in the floor of this dilapidating building, never to be seen again.
Despite being the worst feeling of my life, and being on acid, it wasn't a "bad trip" because it wasn't the trip's fault...
I would be interested to hear about your experiences. username at gmail if you'd rather not share here.
Sure, I've written a bit about one of the more damaging trips I've had before on HN:
