Shelter portion of Bug Out Bags.

Shelter.
So now that we’ve covered Medical supplies, time to make shelter. While there several shelters already made by mother nature, there not always the best, though I will cover a few.
Uprooted trees. You know, the trees that fell over during a storm. If the tree was big enough, the roots are probably a few feet high, perfect. Just add enough limbs at an angle going over the roots, then cover with large green leaves, at least a few inches thick. This shelter can be made with absolutely no tools.
Overhangs from rocks, nice little cozy holes underneath a large rock, boulder, or cliff. Just add a bunch greenery as a mattress and your set.
Now there are a few you can make with a few tools and other things. Also read up on a Lean to, as well. I won’t cover Lean Toos here because there so stupidly easy to make.
Now Dangers of shelters.
§ Poisonous little critters. Things like scorpions, poison snakes, and the like, should be removed from the area surrounding your “Campsite.”
§ Falls and heights. First of all, don’t be stupid. Avoid putting you shelter any closer than 50 feet to a drop or fall.
§ Water. Don’t set up camp in a creek. Seriously. Also be warned, with a cliff overhang, if the floor angles inward, don’t use it. If it rains, you might drown. As in the water will drain into the space your in and drown you (Especially if you’re a heavy sleeper.
§ Falling limbs. You’d be surprised how m any people get hurt by falling limbs, either falling into their tent, on them, etc. Check the area around your “Campsite” to make sure there are none, if there out of reach, DON’T CLIMB THE TREE you could fall and be screwed. And then for irony the limb could fall on top of you. If there is one though, either move to the opposite side or use a rock to try to get it down(Like throwing.) though you’ll probably wont hit it.

Now for man made shelter.
Tents. Best to get one that can fit you plus one. Make sure its waterproof. (Plus you can collect rain water. +1 water!)
Sleeping bags. An alright shelter. Not as good as a tent though, but then again it’s too cumbersome to carry both. I’d recommend a Mummy style bag as it will keep you warmer. Remember to use bug spray before you go to sleep though.
Tube tent. A sheet of plastic that you run a piece of cord through that makes a triangle of plastic. Not the roomiest, but at least its Waterproof!
“Survival Blanket” You know, the aluminum foil type things? They rip extremely easy, so don’t wear your boots while using one, at least I wouldn’t. With some cord and tape you can suspend one in a tree as a giant signal mirror!
“Emergency Poncho” I wouldn’t waste time with these as you can do the same thing with garbage bags. Although I carry 2 in my Bug Out Bag, its for last ditch shelter.

So now, what do I recommend?
A tent.
A VERY THIN wool blanket
And a space blanket.
Now to be creative and waterproof them consider…
§ Some cordage
§ Duct tape
§ Bungee cord
§ Etc.
