The Rim Fire around Yosemite has burned 246,350 acres and is only 80% contained. The larger Cedar Fire in California burned 273,246 acres in 2003 in San Diego County, killing 14 people and destroying 2,820 structures. Both fires were started by hunters who just had to have a campfire. I am sure that the relatives of the 14 people who died in San Diego and the 2820 families that lost their homes understand why having a campfire is so important.
I have learned to avoid areas where hunters will be present having come across too many Rambo want to be guys and having seen a tent in the eastern sierras that was shot full of holes by two hunters who told us that they had seen a bear. Fortunately the couple was not in their tent when the hunters opened fire.
