I think pipe smoking is regional. Some areas seem to have more pipe smokers, hence more used pipes in yard sales, antique stores and flea markets, and maybe a few pipe smokers appearing in public from time to time.
Other places it is rare and unique to see any vestige of pipe smoking. I thought in central North Carolina, in the heart of the tobacco belt, I'd keep an eye out for pipe smokers, used pipes for sale, and pipe shops.
Despite having an excellent independent pipe shop at the edge of a large campus at the edge of the downtown, and formerly having a Tinder Box pipe and cigar chain at the big mall, I have found slim pickings, even at the big flea market at the nearby state fairgrounds.
I'm not sure why. Maybe the area has become so interspersed with non-natives like me so doesn't have any roots this way. Or maybe the cigarette industry was so deeply engrained here that the pipe smoking demographic just faded away. Or some other reason?
My city had one of the best regional pipe shows in the U.S., not a New York or Chicago pipe show, but an expansive good one with reps from major pipe retailers and blenders. This hasn't reappeared yet since the pandemic, but may yet resurface. I'm waiting to see what happens with all of this.
