At the Flying J truckstop in Ohio, near the Pennsylvania border, we observe history in the making. When we pulled in, unleaded was posted at $2.49. Walking the dogs near the sign, I saw broken pieces of plastic—partly transparent, with opaque black shapes. I looked up at the sign and wondered how they changed the numbers. Then I realized the broken plastic pieces were the numbers that appeared on the sign. That left me wondering how they got them up on the sign. Soon, that question was answered. Just one of the rewards of a night at the truck stop—no water, no electricity, no sewer hookups.
