I brought a corn cob to an outdoor concert a few weeks ago and lots of people commented that it was cool or interesting or unique or some such thing. Smoke in the car occasional and see people taking notice.
I took the family out to the local car show today and per usual, I was smoking a pipe as we walked around. As you might imagine, public piping draws a fair bit of attention and sparks up almost as much conversation. Which begs the question, where do you enjoy piping in public?
