i recall a post a few years ago where some fellows here met up and spent a weekend camping with just their BOB's.a bunch of photos were posted of hasty shelters and smoky fires and it seemed to have worked out just great but i never saw any follow up.
by the way if your wondering why i'm up at 12:30 at nite posting away like crazy it's because the pain meds for my bum knee have not kicked it yet and i can't fall asleep--now thats a survival issue!!
