I do it do save money. Most of the places I go here in CA are in national forests. Most national forests allow "dispersed camping" otherwise known as sleeping in the forest. I like to find a forest road across from a campground or day use area along the stream. that way, I have a rest room to use in the AM, but can still sleep in the back of my Ford Explorer for free. I can also get back into the more remote areas and sleep. I usually bring 3 or so gallons of water for drinking/cooking. I use a couple of camping pads beneath me for cushioning. I had the kids at my high school weld me up a bear box for food storage, as I keep nothing a bruin might want inside with me. (i do keep my 870 in there though) I have a one burner stove and a propane lantern. Everything necessary is kept in a camp box in my garage for spur-of-the-moment getaways.
