Driving 63 miles to attend classes costs a lot of money. That is a lot of gas being used up. Keeping the tires aired up and the trunk empty helps keep the gas mileage up. Would be nice to have one of those new Prius that get 38 miles per gallon on the highway. Would save a lot of money on gas..but you have to have the money to buy the sucker in the first place! And those are very expensive.
