>The training must be severe. Back in march of 2010 we took a room in a hotel where we couldn't smoke. Just couldn't find anything else at the time. In the morning, we went out, at the corner of the building, where a group of tourists was gathering. We stood a few meters apart from them, but they collectively chose to move some 20m away from us... straight into their bus's exhaust. It was just idling, and mind you, american diesel is not as clean as european. They didn't mind breathing that, just as long as they are far enough from the deadly cigarette smoke particles.

Maybe those folks were from Los Angeles and needed to get their daily intake of smog?
