Bryant, You have to be on the forum, I think for 90 days and have 100 posts, to access the buy and sell part of the forum. Back in the 60s I had two pipes and smoked six pipefuls a day. I did that for a while before I bought another pipe and it didn't hurt them at all. If you tell my wife that I will deny it. I think all that rotation stuff is an excuse to buy more pipes, but it is an excuse I use.
