I always found it interesting that most of the people I know who go to vegas complain that that casinos are too smokey and they don't like that. Then I went to the Windsor/Detroit area...Windsor went smoke free including the casino and the casino was completely empty. A few hours later I went to the Greektown casino in Detroit where smoking is alive and well and the place was packed. Since there is a country border between them I can't draw too many actual conclusions, but I did find it interesting.
