I've had a couple pipes north of the Artic Circle, which is not especially "weird".
Probably the most unique circumstance I ever smoked in was as a member of the audience at a one-man Mark Twain performance in a tiny theater in Chicago. I was 19 or 20, had just started smoking, and the city was still years away from an indoor smoking ban.
At the time, I thought it was fitting tribute to Mr Twain and that the fact that no one told me out loud to stop was the same as agreement and approval. I consider it rude beyond measure and a regret now. Ah, the blessed, self-centered, ignorance of adolescence...
