Bare minimum... huh... let's see...

1. .45 Colt gov't model
2. thru 5. extra magazines
6. thru 10. rolls of twenty dollar gold pieces.

Just joking (sort of), considering the time of year, my location (Illinois), and the JUST PLAIN WEIRD weather that's been drifting around me and my neighbors (Indiana, Iowa, and Kentucky), I don't think I'd "bug out" with only ten items, regardless of what they were (unless I was ABSOLUTELY sure that those ten items could get me anything else I might need).

But just for yucks...
1. Bowie knife
2. Ferro rod
3. wire saw
4. small skinner
5. .410/.45 pak gun
6. poncho/liner/survival blanket (if you count this bundle as three items, I'm S.O.L. I consider it one because its my bed-roll, same as a sleeping bag)
7. Hennessy Hammock (yes, even in the Winter)
8. Ceramic/charcoal water filter (the brand name evades me at the moment, hose & pump, currently (I think) being issued to Marine recon units)
9. and 10. A.L.I.C.E. canteen/cup/carrier one for each hip

I normally wear/have immediate access to three or four layers of warm, weather resistant clothing due to my line of work, so I've chosen to ignore the winter wear issue, and there you have it.
