The one thing that is mandatory when we camp, is a nice fire in the evening. I agree with johndar... the please dont use the fire pit as a trash can, I am amazed at what some people put in there, thinking it will magically "go away". We have been to some campgrounds on a weekend ( what a mistake!) and the amount of smoke was so bad we closed the windows and went in early to avoid the smog, but we asked for it. I didnt go out and yell at my neighbors, cause its their right to enjoy as they see fit.
As it is here in our locality the wood Nazi's only allow us to bring campfire wood that is de-barked from local area's. I cut down only the dead ash trees on our property for fire use. Stop the madness. Its only a campfire.
