I don't see many pipe smokers but I see them. I was in Alicante, Spain, last year, and saw a pipe smoker while walking the streets. Then up in Madrid I was sitting in a little park, smoking my pipe, and I saw old guy smoking his pipe too, waiting for his wife to come out of the market. Here, in Florida, a kind gentleman down in Tampa let me ride his bad ass moto guzzi while he rode my little Kawasaki, and when we stopped for breaks, he'd smoke his pipe.
But in general I see fewer pipe smokers in the U.S. I see people smoking swishers, black n' milds, cigarettes quite a lot, and we'll nod or talk but no one comments on my pipe and I don't comment on their cigarillos or cigs.
I bought my first pipe in Nottingham, England, and I used to see pipe smokers there--but that was thirty years ago.
