I've been to many Grateful Dead shows, but this one incident stands out. It was my wife's first dead show and as the band broke into an encore all of a sudden the crowd started to part - like moses doing the red sea. Shortly after the crowd separated we saw wgy.

Here comes this guy, he running and stumbling thru the crowd, and anyone who has any liguid at all near them, he's grabbing it and pouring it on his head -- sodas, coolers of ice, beer .. whatever.

As he gropes his way closer I could see his eyes wide open and fully dilated. He had green snot (and I mean like LIME GREEN) running out his nose -- as we were about to grab our stuff and make a break for it he got tackled by about 7 security guards and hauled off.

Whatever it was, he was TRIPPIN -- worst experience I ever saw. I've seen several people lose it -- be he takes the cake.
