I think it was Best Buy, but one venue had cops in the men's room. Somebody asking for drugs could be undercover...or is that entrapment?
Trippin' at a show...hmmmm...keeping in mind and respecting set and setting...definately.
I respect those who choose not to (I respect the Warfrats as well). There are plenty of ways to be high and happy.
Has anyone mentioned Contact High?
I think Furthur puts something in the air at shows....
I find the west coast, and Bay Area especially, to be more psychedelic, both the music and the audience. I expect Eugene, Red Rocks, and Monterey to be the best shows for trippin', but you never know.
Historically, the connection between LSD (and other psychedelics) and the Grateful Dead is significant, both in the creation of music & lyrics, and in audience participation.
