I personally don't smoke - hate it. And I'd love to go into pool halls that were smoke free. But I'm not going to complain too much, because the pool hall isn't mine, it's a place I choose to go. I deal with it.
I don't know why more pool halls (at least the ones that make good $$) around here don't buy better filters - like top of the line shit - because I know of ALOT of people that like pool, but refuse to go to a pool hall because "it's just too smokey".
I'm also convinced that myself, along with everyone I know who is a regular pool-hall go'er is going to get lung cancer and die.. but it's cool.. I don't plan on living that long any way, lol.
