I filled up with gas again a few days ago--only $64.50 this time! Previous fill-ups were $70 and $66, so I think I'm beginning to see a trend! (My signal to get gas is when the low fuel warning light comes on, so I think I can trust that these numbers reflect comparable levels of emptiness.)
Chess camp is over and all the choirs are winding down for the summer, so I'm expecting this most recent tank of gas to last a while. Fill-up was four days ago and I still have over three-fourths of a tank remaining, so maybe this time I will actually make it two weeks on one tank.
Hope springs eternal!
