I'll take the heat for cheating up front since I have gear bagged up in the back bedroom that has pretty much all I'd need (boots, clothes, rations, navigational gear, med kit, leatherman, chemsticks LED flashlights, etc.) packed in an old canvas seabag, so that's item #1
#2 - My S&W 39-2 sidearm w/shoulder holster is a must...(additional mags/ammo in the seabag)
#3 - The situation would dictate which automatic rifle I brought...if it's civil unrest/natural disaster, then I'll stick with my .30 Carbine (ammo/clips bandolered), but if it's a foreign entity (which would most likely sport warsaw pact weapons) then it's my 7.62x39 chambered AR...that way I can travel light and resupply as I go
*if* it's really ugly out there, then I'd bring additional heat to the party in the form of my Remington 12 ga. Autoloader and a variety of rounds because asshats come in a wide range of stupid...this would be #4
#5 GMRS two-way with weather for communication with friends, info, etc. (cell service would most likely be down in a worst-case scenario)
#6 my bigass knife for those times when you just absolutely have to have a bigass knife...
And well, that's pretty much it. I'm not one to drag a ton of stuff with me, it'll just wear ya' out and you'd probably end up dumping alot of it along the way anyhow. Hope things never get to this point, honestly.
Also, a little tip for anyone who wants to know a good way to start a fire in about any condition: bring a couple wads of fine steel wool and a 9 volt battery. When you need to light a fire, take some steel wool and touch the 9 volt battery's terminals to it...have your tinder handy because stuff will be happening pretty quick.
