Christ...I don't bother going to D.C. unless the Bruins are in town playing the Caps and both times last season got nabbed by cameras. Eff D.C.
That's one of reasons why I park at Shady Grove and take the metro in for Caps games. No parking fees or tickets plus it also allows me extra time to sober up after enjoying celebratory beers.
You're harshing my mellow man. Maybe I will walk.
If you have to drive through there, just play along. No matter the posted speed limit, drive at least 10-15mph below it. Before long, the cameras will be gone or reprogrammed due to the city grinding to a halt and tens of thousands of complaints from angry residents.
