Nahhh Dennis, you're not a snob!
The problem with common sense is that it is very uncommon....
I try my best to burn good clean dry wood in my campfires. If I am going to stink and go to bed like that, I want it to be pure stink, not polluted!!
Anyhow, kidding aside, I agree with the comment about burning every kind of crud you can find. I do burn some garbage, but it is only done when the smoke cannot infest somebody else's olfactory system, including my own. Better to burn a bacon grease soaked paper towel than toss it in the CG bin. I've had enough bears trash the bins in the night in search of a meal.
Yeah, common sense, learn it, exercise it!
