Bill,
Ironically, in yesterday's Shreveport Times there was an article stating that a proposal is on the books to ban smoking in all public places in Shreveport. Of course even if it passes it will be too late to affect your gig Saturday.
BTW, it looks as if I may be able to attend after all. But if it's as smoky as you say, I won't stay long!! I worked there several years ago, and don't recall the smoke being that bad.
