I smoked cigarettes for 17 years (and have quit for 18 & counting). I won't give anyone the business. But I have noticed that I just don't like tobacco smoke. It's funny - driving down the highway at 60 m.p.h., if the guy in front of me is smoking a cigar, I smell it. It's not a problem, but it is funny how a cigar can be detected on the open highway. My next door neighbor smokes grape cigars. My wife kind of likes the smell (not so much for me).
Smoke rising: We specifically request 3rd story rooms at CN so there is less of a chance I offend anyone with my smoke.
