In Florida at least, it's not optional. If you're wheeling in a national or florida state forest you're required to have a hatchet, shovel and fire extinguisher at a minimum. The reason is that some of our FL wildfires have been caused by 4x4s and ATVs hot exhaust touching dry tinder.If my FJ ever catches fire I'm gonna let it burn. Then I get a new one. Who wants a half-burnt FJ Cruiser anyways?
