Taking it off

I'm driving back to DC via another (and a bit longer) road. We've almost reached the highway and I'm getting a bit tired. A quick look into my rear-view mirror wakes me up completely. The 18-wheeler behind me has a huge confederate flag pinned down to the front. I've never seen this flag displayed so prominently. We're still in West Virginia, approaching the border with Maryland.
The truck is going much faster than I am. It passes me and disappears. About 20 minutes later, as we have already entered Maryland, I spot the truck on the side of the highway. The driver is walking toward the front. I surmise that he wants to get ride of the flag before keeping driving. After all in Maryland, this flag will not go unnoticed. I pass him before I can check if I was right.
