Last time I filled up I calculated: My current (at that time) expense was 6 miles to the dollar. Thats right, each dollar of gas takes me all of 6 miles... well with the increase since then it is probably closer to 5 miles a buck now. Thankfully I can take public transport to work most days, but still, I have to think hard about all expenses, any 'extra' trips, and it SUCKS.
