Amen, gtblum. Just by coincidence, I used to work on a dairy farm in New Hampshire back in the stone age. I didn't know it but I smelled like manure everywhere I went, I was so used to it I didn't even notice. And since most of my family are ex smokers, I realize how sensitive they are to the odor now, and I do try to be considerate. However, we're talking about a SMELL, not something that is harmful to one's health. The smell of BS never hurt anyone, and neither did the smell of cigarettes. It's the research that says 2nd and 3rd hand smoke is harmful that I don't trust. sorry, they've lied to many times.
