I should have checked your profile- you're IN Alaska! For what it's worth, I spent a year in Unalaska- no oil, but alot of unspent 50 cal. shells from the war. I doubt anyone's car would run very far on that...
No kidding. 50 cal shells, de-primed and cleaned go for something like a dollar each. Talking with some old-timers, still a few around: although the Japanese never got to Fairbanks, they were ready for them; it would have been a fight.
