In 1992 as well as 1990. In '92, there was these 2 cops that were walking around the lot that allowed folks to put bumper stickers on the back of their big leather coats. I wish I had a picture of it. They even lets us have a barrel fire on the lot since it was freezing and they came by to get warm a time or 2.
No problem getting back into the US in '90. 1992? - not so much. Huge hassle, searched, and mildly interrogated. Even after that near miss, my brother and I were heading back to Detroit after Phish New Years in MA (1992-1993) and thought it would be a good idea to cross over into Canada at Buffalo and come back through Detroit. Again, no problem going in. THIS close to long-term incarceration coming back though. Rental Car, couldn't find paperwork, long hair, zero sleep in 3 days - pretty smart, eh? Turned ALL our stuff inside-out except for my well-worn Hitchhikers Guide to the Galaxy. Had he leafed through that classic, we woulda been looking at a stretch in the clink. Whew.
