We joke about it because I put zero stock in the whole Mayan calendar crap. I'm not worried that I will be able to drive back home with no problems. But I took this opportunity to exercise building a GBH bag. (Get Back Home). It was a good exercise, and I learned that I may need a bigger sack in the future. But I got it all in. Here's what I surmised: 275 miles away, would take about 7-9 days to walk home if need be. I packed 9 days worth of Mainstays and three cans of tuna, along with some simple sugar products for quick energy. Water purification tabs and a filter straw and will put as many bottles of water (bringing a case in the trunk) in the pockets outside the bag. Knife with paracord and magnesium stick first aid kit New, insulated hiking boots (worn in around the house) with two extra pair socks Flashlight, full Zippo with new flint and extra flint Baggie with two socks coated with Vaseline Walkie Talkie, solor/battery/crank multi-band radio with USB charger via crank if need be - all sealed in a mylar bag Rope, duct tape, cable ties 50 round box .380 for carry (half FMJ, half JHP) One clip (in gun, JHP) two extra clips (FMJ) Two loaded 30 round clips for my AR-22 Ruger (Ruger 10-22, AR platform) Leatherman multitool and jewelers screwdriver set. $3 face value silver dimes Thunder 380 and the Ruger 10-22 (with 25 round clip loaded) slung in case My wife and daughter know if something happens, they grab my .45, wife's TCP the 22 magnum pump, , extra ammo, the other walkie talkie (in a sealed mylar bag), load 5 extra 5 gallon gas cans, and crank up the 76 GMC Sierra and start driving. Once they drive about 3 hours, they start squawking the walkie talkie every thirty minutes or so. So how did I do? What did I miss?
