When I was in Washington, D.C., over the weekend, I encountered a food truck parked next to the Woodley Park Metro station. A crowd of people waited in line next to the truck, with wallets wide open and hungry for lobster.

The District is evidently friendlier to mobile vending than certain municipalities in the Saint Louis region, which may even be losing some business to the D.C. area. Pi Pizzeria of Saint Louis has been restricted from Clayton, Mo., and Edwardsville, Ill. — but it expanded into the D.C. area this month! Although I can’t suppose that the Pi food truck wouldn’t have gone to D.C. anyway if the Saint Louis area were wide open for Pi’s trucks to do business, I do find the coincidence interesting.

Who would have predicted that there would be such a demand for lobster from a food truck? I bet that it wasn’t a government official.
