Pillowcases, I don’t need no steenking pillowcases!
Step 1; grab fully stocked Bugout Bag backpack by the door (it contains freeze dried food, water purification stuff, firestarting supplies, first aid kit, flashlights and batteries, a couple good stout blades, a “space blanket” tarp, and an old WWII style entrenching tool), stuff in the magazines for my Glock 21 and CZ-75, a couple boxes of ammo for each, holster on the Glock, slap in a fully loaded mag in the Glock (13 rounds of .45 ACP goodness ), put the CZ in the BOB
step 2; grab my MacBook, and flashdrive with copies of important papers on it, hump the BOB and MacBook down to the car, toss them in the back seat
total elapsed time 5 minutes or so, with the next 5 minutes, I load up the rest of my firearms, and my ammo supply into the car
Step 3; the next 10 minutes are spent grabbing some canned goods from the pantry, a couple 5 gallon water bottles of water that I keep pre-filled for emergencies, some cold weather gear , and finally, track down the two cats and take them with me (that’ll probably bring me right to the 20 minute cutoff point)
having a Bugout bag ready to go cuts down drastically on the preparing-to-go time, just grab it and head out the door
