Just filled up the car today. Here in central Illinois it hit the magic 3.99 a gallon. Calculated my MPG and I'm got 32.8. Go easy on that gas peddle and slow down helps.
I take 5 to 6 trips a year and save up for them, for the gas and the supplies. If I have any cash left over on the way home, I stop and have a steak dinner.
One problem I've encountered is the darn gas stations don't like cash anymore. They make you prepay if you don't swipe your card into the pump.
But, I'm a creature of habit. I seem to always camp in the Ozarks somewhere, either in Missouri or Arkansas. Trips of 250 to 400 miles one way.
