You guys should have seen the Emergency Zombie Survival Kit a mate and I created while we were deployed to Iraq last year. It contained two crowbars, a combat lifesaver kit (mega first aid pack), a machete, two aluminum baseball bats, we each had a pistol, an uparmored HMMWV (HUM-V in civilian talk) several gallons of water, two camel backs, 50 MREs, a range finder, binoculars, a bag of tactical equipment and several changes of cloths, 25 gallons diesel fuel, 1 rope 100' long, a small shovel, maps and a plan to bug out if necessary. All stored in two tactical backpacks in the back of the HMMWV for a quick out.
I'm in the process of building a similar kit at home. Currently I have the bat, the machete, a "CLS kit" of sorts, a pistol, water, MREs and a plan. But that's about it. I need to boost it up!
