I know it's not good in aggregate, but I miss smokey bars, even though I don't smoke myself. The smoke made everything look sort of softer, and the smoke hid some other odours of bars. :-)
There was also a defacto "tradition" on campus, you saw coats and shirts on balconies and then you knew they'd been to a bar last night. :-D
I thought I did too, but now I live somewhere where there are plenty of smoky bars, and the novelty wore off quickly. It's just a pain having to deal with clothes drenched in smoke after an evening out, when you have experienced not ever having to deal with that. Knowing that all bars are smokefree is much easier than having to remember which ones are and which aren't.
