I have been primitive camping for 3 weeks. I will most likely free camp in a national forest tomorrow,and for awhile. What do I need to be weary of when dispersed camping in a national forest? Besides the usual camping basics, wildlife, plants, etc.. It's me (30m), my dog (4m,75lbs), and my car. My dog is greatly trained, I have a couple knives and a staff to protect myself. I'm sure it depends on which forest, can I also reach a site with my car, or is there a decent place to park and hike?
