found an interesting site that lists gas prices in san francisco: http://www.sanfrangasprices.com/

it appears to be rather comprehensive. having a motorcycle as transportation is definitely less gas-expensive than a car/suv, but i’m noticing that what it costs to fill up my 2.5 gallon tank (which gets me 110 miles of driving, or about a week’s worth of commute back and forth to work, if i don’t make any side trips) is definitely more than what it cost 2 years ago.
