My SHTF bag has some new contents....thanks to all! I have a tac vest (Cheaper than Dirt) easily loaded with my .40 Witness compact & 3 extra mags (loaded), compass & whistle, LED flashlite, P-38, 10 SKS stripper clips (200 rnds), leatherman, cheap poncho, tactical goggles, binoculars, 2-way radio, knife, matches, firestarter & 2 cans potted meat. I have a tac thigh holster w/ 1911; canteen & 5 mags on belt. Oh, and an SKS will be slung over the hanger (after Christmas!). All I need to do is put on the vest, insert pistols and haul ass! My wife gets the 12 gauge & ammo belt.
My bag (fits nicely in the truck's toolbox) is a seabag with 2-man dome tent, 100' para cord, 200 rnds. of .30-06, 5 gal. bladder, 3 days of clothing (inside compression bag), 2-pk boot laces, spool of 17# test fishing line, sinkers & hooks, camp shovel, cy-lites, matches & sticks inside 2 ziplocks, field first aid kit w/ lots of goodies, machette, sm. box of stuff (misc. screws, bolts, nuts, twist-ties, washers, etc - 8 oz total), sleeping bag, 3 ponchos, snakebite kit (updated version), 3 cans of SPAM, Louisiana hot sauce, hand warmers, folding bone saw, 12 gallon-sized empty ziplocs, respirator & extra filters. Too heavy to carry far (which is why it's in the truck). I think I will add a few short pieces of PVC tubing (slightly larger than the diameter of a 12 ga. shell & about 6" long), end caps, roofing nails and 10 rounds of #4 shot (to establish a perimeter around my base camp).
The Alice pack (never far away and can lay at the very top of the SHTF bag) has one can of SPAM, 2 oz earth-scented gun oil, breakdown .22 cleaning rod, patches, knife sharpener, TP, travel pack baby wipes, gloves, hats (boonie & stocking), face paint, poncho, 50' nylon cord, water purifier, sm. first aid kit, wire saw, 24" picture wire (can double as snare), space blanket, 1 oz tube of liquid graphite, ammo wallet w/ 9 rnds .30-06 (in double ziploc), ammo wallet w/ 10 rnds .45 & 10 rnds .40 & 5 rnds. for SKS (ziploc'd), bar of Ivory soap, toothbrush & paste, spare Rx glasses (good to see with & start fires!), 2 cy-lites, 3 oz scent blocker, 3 oz fox urine, mini-mag lite, $20 bill, 5 $1 coins & 4 quarters, 10 yds. duct tape, 4 pr. latex surgical gloves, whistle, compass & signal mirror, matches & mag. firestarter, knife, leatherman, 33 gal. 3-mil trashbag and a hand towel. I have carried it through the woods for 12 hours with no major issues.
The truck has other stuff tucked here & there. Husky Jump-Start system w/ lite, hand axe, tree saw, mag-lite, 2 gallons of water and a bunch of odds-n-ends. Canned food can roll around the bed if need be.
We can go if we need to (worst case), but we are likely to stay put (grid-lock). Best case is to go about 20 miles to a friend's house cuz he's got a secure location that is well-stocked. Word of advice: if you meet people, bring something to the party. Same goes if you intend to host. Tell people to bring something - don't show up empty-handed, lest they be turned away!
