For camping: Campgrounds for Camping RV Parks, State Parks USA

Fiddle around at this site to filter what you want. Best I've seen. KOA's are often nice places, but can be expensive, and may not always allow tent camping. Wild camping is nearly always possible if not too picky and you know how to do it. Never had any problem with animals or humans.

The burner and Coleman gas cannister in BobG's post is inexpensive and practical, except for the bulk. Kinda depends on how much cooking you expect to do. I carry an MSR Pocket Rocket, but the gas cannisters are usually only available in the big, chain outdoor stores like Gander Mountain, Academy, and Bass ProShop. Expect about 10 days/large size, light to moderate amount of cooking. I usually just heat some water for morning coffee and oatmeal now and don't mess with much actual cooking. A lot of people seem to like the Jetboil system.
