Our office is in downtown. Railroad tracks run through downtown, dividing the east and west sides. Tractor-trailers aren't supposed to go across the railroad tracks. Still, sometimes they try. And sometimes when they try they get stuck. Yesterday one got stuck just as the afternoon train was coming through. Chaos!
I took a picture. Click on it for the full effect -- it's pretty funny. Note the bright yellow warning sign and the position of the railroad-crossing arms (what do you call those things?). That was one stuck truck.
