Maybe I'm insensitive for some reason, but I think that if a person is sensitive or offended by smoke from a campfire or someone's smoking a meal that perhaps camping isn't the best recreational outlet for them. There is no guarantee that the same problem can't arise from someone in your own neighborhood who might be grilling or using a smoker or have a fire pit on their patio. I tend to have problems with pollen from conifers. Does that mean I should have the right to ask to ask campgrounds not to plant pines? I tend to feel that I either have to suck it up and take medication that alleviates the problem or stay home...where there are still spruce and pines.
