Its cooking smoke as stated earlier,, by all means fire it up,, If you are down wind and don't like it..MOVE!! Or find another hobby in a clean room!!
Who in there right mind would complain???
Let me see,, you paid for your spot just like every one else,, Smoke dog rockets,happy logs,what ever,,,, I camped next to a couple that sat out and drank a 48 pack of beer and smoked a pack and a half of cigarettes EVERY DAY!!!
I didn't complain,, If it bothered me badly enough I would have asked for a different spot,,, It's Camping!! Enjoy!!!
