As a society we've come a long, long way on protecting non-smokers from second hand smoke.  In 1962 I sat in a University of California classroom while the prof chain-smoked through every class session.  Restaurants didn't even have a "smoke free" section.  It wasn't considered rude to smoke in such public places, it was "rude" to be bothered by the smoking and say something.  Today 22% of adult men and 18% of adult women smoke.  In the '60s, those percentages were double that.  Things have changed....and changed for the better. 

Sensible County Park regulations should be achieveable..  Mr. Stewart's suggestion regarding ceremonial smoking shouldn't be difficult to include and exempting camp sites makes real sense as well. Some additional designated smoking areas would also be easy to define.

It really shouldn't be THAT tough to develop a policy which protects non-smokers from second-hand smoke, while providing reasonable accomodations for smokers.  A reasonable compromise, please
