Where I go, my pipe goes. Walking, driving, etc... I love that it gives me the excuse when I escort my wife out shopping to just set outside and wait on her while I smoke. I meet lots of great people this way, because for some reason an old man smoking a pipe seems to be everyone's invitation to just down and spill their guts. Sometimes I don't mind, unless they start asking a bunch of questions, wanting me to respond while I am clenching. I usually just politely tell them that I am smoking and I'll listen, but I'd rather not take my pipe out. If that doesn't work, I'll just follow up by getting up and moving.
Worst is when someone wants to know how to get started smoking pipes. I have a set of cards with our pipe clubs info on it. I'll hand them one, but if they get all impatient demanding answers, I just tell them that obviously they don't have the patience to be a pipesmoker. Make them work for it... I will usually see them latter on at a meeting. I am certain that if this is made to be seen as just an easy hobby to get into with cheap supplies, that most wouldn't even bother. But, I digress...
