Gas Mileage

Do you keep track of your gas mileage? Normally I don't but when we travel it is something I do write down. Of course we get better gas mileage on the open road compared to just driving in our town. When we do take trips I don't really get too worked up about gas prices because we are going to need gas if we want to go places. We do watch for stations that have lower prices but even on longer trips, a few cents per gallon really won't determine if we will travel or not.
