I love going to restaurants that were built when smoking indoors was a thing and trying to figure out where the smoking section (or non-smoking section in older places) used to be. There are a few bars around that still have smoking sections in my area but the requirements are more stringent now (closed room, seperate air handling system).

One of my favorite bars in college allowed smoking upstairs (and still does, although how many college kids actually smoke?). I really do miss having a cigarette in one hand and a frosty beer in the other.

The good ole days ;)

In San Francisco, you can still find buildings where the elevators have ashtrays, though usually the actual tray is gone.
