You could always get the military MREs instead of the civvy ones then dispense with the TP completely if your putting together a 72hr BOB.
Yup, no need for TP at all... At least not for 72hrs.
Ha! You don't know my bowels.... OK, TMI. I probably can get rid of most of the TP though.
Good idea with the shells with the rifle, SBRaider. However, then there's an issue with safety, in terms of ammo seperate from the rifle. It has, however, crossed my mind.
One of the other comments regarding my environment: Fairly good fitness level (run 2-4 miles, usually 5x/week). The asthma is fairly well controlled. Family within 45 miles east, or about 180 miles north. After that, nearest family is about 8 hours away by car. Living in metro Detroit right now, so I can either stay urban, or probably hunker down in some of the larger undeveloped land tracts around.
Experience: not much camping lately, but I started at 6 years old, did Boy Scouts through 18 (eagle scout), mostly in the CA mountain ranges. Didn't grow up with "seasons" like they have out here, so I probably overdo the cold weather gear a bit.
Cash: I'm a student. Limited, but enough to scrape up some gear. Assuming there's some time, I might strap on my tent, bivy bag, or sleeping bag from my camping gear.
Thanks for the comments so far everyone.
