This may be pushing the 5-minute mark, but this is what I had ready to take with me on Monday.
My Girlfriend had all the important insurance and tax documents, which of course I would have forgotten!
That's my Wallet, Keys, P3D CE with 4 spare batteries (nylon case), Binoculars, Multiple Handkercheifs (probably 4 more not pictured), 2 pairs of Jeans, a Bedroll, a couple of tough-as nails Army Surplus bags, 2 bottles of Smartwater, Trail Mix, my Girlfriend's misc. clothes (the bra's not mine), my misc. clothes, Notebook, Running shoes.
Not pictured: Pepper/CS spray, Inova X5 flashlight, Fixed Griptilian, Mini Griptilian, Garmin GPS, Compass, Windproof lighter, homebrew "Survival" kit, 2 pairs of flip flops (mine and the GF's), a Glowstick, several Keychain lights, a Benchmade/HK folder, 8 Clif Bars. There's also a 'big' first-aid kit with emergency rations under all the clothes, and a neoprene arm-band wallet with about $50.00 in bills in it.
Sounds excessive when I list it all out, and I suppose the backpack is 'cheating' a little, since it stays loaded with most of that stuff regularly, I just shoved more in getting it ready.
