I've got about the same thing, three tanks of gas a week, there's no way to "stock up", except to fill the HHO tank, maybe, though I cringe to do that at 2.35 gal for HHO, but I guess it's not going to get any better.
Anyway, doomday senario aside, I am wondering if I should throw my AK and a few hundred rounds in the trunk in case I get caught far away from home in a shitstorm.
Probably not.
I doubt you would have a problem if you were to break it down, place the '47 in the trunk and the ammo and clips in the front. Better safe than sorry.
You mean you need an excuse?
