The prices I'm mentioning are for regular; that's all we use.
Except for the RV or going geocaching, we seldom drive more than
10 miles round trip. On vacation gas averaged $3.43; but yesterday when going to church, I saw signs for $3.79 at several
gas stations. That's quite a jump in less than a week's time.
I generally don't let the tank get below 1/2 full, especially in the wintertime; once in a while, it gets to the one-quarter mark. But not often.
