I am about to move to Washington state for my new duty station (fort lewis) and I will be making the trip from Lewis to the yakima valley every other weekend or so, so I will modify my current kit as my needs change.
Right now, I have a 1972 Ranchero that I drive around town and occasionaly take out on the highway a few hours north or so. So I have an aluminum toolbox in the back with the following, (a * denotes its on the list, but waiting till payday):
Jumper cables
Fix a flat
Tire gauge
Tool set (sockets and drill and wrenches)
tire iron
scissor AND bottle jack
Combat Life Saver bag behind the seat (thank you US Army, still need new IV bags though, contains everything from gloves to a splint to tape to scissors, basically small EMT bag)
big flashlight in the back, two small ones in the front
*flares
*fire extinguisher
*blanket
my carry gun at the time (i live on post, otherwise WASR-10 with folding stock behind the seat with two mags)?
*the jumper thingy? you know, the thing that jumps your battery by itself? this thing:

spare tire
*maxi-pads (can be used as a impromptu field dressing as well)
*MRE's
Once I get up to Washington again I will look over and revise my kit so that I am ready for anything. my fiances mom was trapped on the pass for half a day last year, and people get snowed in all the time. **** happens, and its better to have it and not need it then to need it and not have it. isnt that why we carry firearms?
