I was reading a thread on another board where someone forget their wallet, but was low on gas & had to drive about 35 miles to get home from work & was asking if they'd make it if they had 2 bars showing on their gas gauge. Well, 2 bars, doesn't tell us much, but it got me thinking...how many of you hide a good amount of cash in your car for emergencies? I never have, but it's probably not a bad idea. I've only kept change. By the way, posters were telling the person to try to borrow $ from someone at work. Others were saying the person would probably make it since there's a reserve amount of gas even when the gauge shows empty, which many of us know. The question is, was it enough to still make it home?
