When he heard the truck backup beeps on Storrow Drive, he knew some trucker was doing a Backup of Shame

Shamus Moynihan was gliding along Storrow Drive inbound this afternoon when traffic suddenly stopped.

And then he heard truck backup beeping.

Sure enough, a box-truck driver was shame-back-upping on the entrance ramps from Kenmore. The truck is from J.A.R. Bakers Supply, which, technically, is out of state, so maybe the driver needed more reinforcement than the "CARS ONLY" signs, but it's barely out of state - Lincoln, RI.
