gasoline?

I put gas in my car again today. For first time since the end of august. Since I quit my old job I just don't drive any more. I walk to classes (usually) and seem to only drive on sundays when I go visit whichever parent's turn it is to feed me food that isn't microwavable. I hate driving, so I normally ride with other people when I go somewhere. Course I don't usually go anywhere so I don't really think it matters. I think I need either a bigger gas tank, a more efficient car, or I need to drive less. I think it is important that I can fill up my gas tank quarterly simply so that I can track my gas usage in terms of my "4th Quarter Gas Tank". Maybe I should go outside more. Or maybe I'm environmentally minded. Naaah.
