So some guy up in Minnesota rigged up a pump in his truck to siphon gas from other cars into his own.
Maybe I'm a goody-goody, but if I couldn't afford to gas up my truck, I'd cut my losses, sell it, and get something that's cheaper to own. Or start carpooling. Or take a bus. Or ride my bicycle. Or something.
(Thanks to Gary for telling me about this asshat)
