I find myself doing double takes around here when it comes to license plates. On one hand, I see just more Florida plates than I do for any neighboring states (excluding Virginia and Maryland, of course!) I found it odd until I learned that military families don't have to relinquish their home residence status if Uncle Sam's shipping them all over the country. Probably why I saw so many out-of-state plates in the parking lot at school.
On to D.C. plates. Until I moved to the DMV, I had rarely seen an actual Washington D.C. license plate. Since moving here, I think I see diplomat plates more often than actual District plates. It makes me think one of two things:
One, why'd that person cross the Potomac? In the case of my District friends, it takes quite an event for them to cross the river. For the most part, if it isn't Metro accessible, they're not going. More often than not, it appears that they've just left to go shopping somewhere nearby, get some cheap gas, go to work (?). I guess the Target in Columbia Heights is too far out of the way for some!
Two, the double take in my brain reprocesses, "Wait. People that live in the District have cars? Since when? Cash for Clunkers must be working!"
