When I camped and hunted, I would just take a 8x8 peice of treated canvas and some rope and make a lean too or a plow point type shelter,(some times referred to as a diamond wedge. It was easy, fast and real portable. I have at times made brush camps too.
I usally take at least 1 wool blanket rolled up in the canvas and I have a haversack I throw a small copper boiler and a small fry pan in, with a bag of coffee, raw cane suger, cornmeal, salt, peppercorns, boiled beef, cured hog jawl, dried fruits, parched corn and jerky. (The beef is boiled in water and vinager and will last a very long time) !
I like to find a good place up on a flat some where above a stream. I boil water,(am thinking on getting a purifier though). I'll set camp at least a couple hundred yards from where I expect to hunt. If I can find a "reflecter" rock that's a bonus, or a blow down root ball. With a small camp, I have'nt see where it spooks the game away. I was cuddled up in between a couple of rocks one day, built a small fire tring to get warm and had a deer sneek up on me and peeked over the rocks to see what was going on, we scared the heck out of each other too !
I build a "star fire" at the end of my canvas and hang a peice of rope from the pole or what ever, with some hooks I made to hang meat on to cook. You can let it hang half a day and it'll be fine. With the star fire your getting more heat then flame and the wood last a lot longer as well.
It's been a few years since I've done that. When I get back to the Atlanta area, I'm gonna start again, it's been way to long.
Last time was about 5 0r 6 years ago, at Pine Log WMA here in Georgia, on a hog hunt. There was 10 of us, we walked about 4 miles back in there and set up for 3 days. We had a good time. I showed them how to prepare bobcat for table fare. No, they don't taste like chicken, they taste like what they eat, that one evidently ate a bunch of rabbits LOL!!
