I noticed that Washington DC is counted 2x in the survey. 1.19% are from the "District of Columbia" and 1.19% are from "Washington D.C." Any idea if there are really 1.19% x 2 = 2.38% from DC? That would be a high percentage for a very small patch of real estate. Then again, I just randomly ran into 2 different TWs (and their riders)that I've never seen before in DC, so who knows!!
