Smoke sets me off into coughing fits that are disgusting to witness. We love a campfire, but I don't get to enjoy them with DH very often. Every now and then, if there's an air going and I sit upwind, I can get away with it.
If someone is smoking something, I just have to stay inside the RV with the windows closed. In a CG situation, I can't find fault with someone who wants to smoke their meal. I just do what I have to do so I can breathe. After all, that's part of what camping is all about. Outdoor cooking, etc. It's my problem and I don't expect the world to accomodate me.
