Where In The World Is The C-SPAN Bus?

Spotted around town- the C-SPAN bus. Can you guess it’s location?

>>There is no prize, just the glory of being mentioned on FishbowlDC. Congrats to those who guessed correctly that the bus is just parked in front of C-SPAN at 444 North Capitol: Rick Blum, Reid Wilson, Bill Shein, Joy Yearout and Steve Chaggaris.
