It’s an advertisement for Colombia—-Not the District of, nor the road. The country: Colombia. I was in Adams Morgan last night and I didn’t see it. So I think it was either dropped off incredibly late last night, or this morning.
See a more detailed shot below the jump.
That full URL seen above is www.colombiaespasion.com, which seems to be a website for a Colombian tourism board. Sidewalks are public property though. So the question is: Did Colombia clear this with the District of Columbia?
