I'd like to offer a couple of thoughts...

Don't quit smoking during this endeavor. Definitely quit when you come back. If you go out there nicotine deprived everything that goes wrong no matter how insignificant will seem as if it threatens the very existence of our universe.

I've used it for some ultralight weekend camping and it's great. No fuel to carry and it burns hot.

I like the Hennessey hammocks, but I like sleeping on my stomach more which is awkward in the hammock, so I don't own one.

Definitely take a tarp, an emergency blanket (the shiny space type), as much twine or cord as you feel comfortable, duct tape, and a good, sharp knife.

This has been a cool thread. Lot's of good comments. I'm anxious to go camping again!
