Popular? I guess it depends on your definition. And, it could be just in certain areas, but I do see and meet more pipe smokers out and about. But, it could also be that I have just been more aware and looking for pipes these last few years. At least I know of quite a few pipe smokers in my area. I can't speak for the rest of the US. But, at least there are always a steady flow of young folks taking up the hobby at The Briary. It seems every time I am in there he is giving the "this is how you smoke a pipe" speech to someone. And, he had to hire a helper to keep weighing out aromatic orders for the newbies from the jars.
