Rolling Stone and Gasoline

Moss doesn't grow fat on a rolling stone, and vines don't grow on a rolling automobile.
Such is not the case with my truck, though. I've been favoring the bicycle so much lately that viny vegetation from a nearby hedge started growing up my aerial.

The last time I bought gasoline for the truck was back in April. Since then I have driven 266 miles, using 14.6 gallons of gasoline.
At this rate, I am filling up my truck about four to five times a year, spending perhaps $120 - $150 a year.
