smoking ban questions

[cowhead]

Alrighty, here in the lovely progressive little town of Lawrence Kansas, the city commish is trying to pass a smoking ban in bars, resturaunts and all public enclosed places. (I've been to California and yeah.. it more or less works although some of the places we went in Oakland offered us 'candy dishes' aka. ashtrays) and I'd like to say I have no problem with banning smoking in resteraunts.. but shouldn't it be the owners choice wether or not to have his/her business smoking or not? that seems to be logical to me... (maybe I'm crazy).

so I guess I was wondering if any of you live in a community where a smoking ban has been passed and what if any effect it had on local businesses. (especially Bars and Music Venues)
