State Avenues

I'm about to confess something that I probably shouldn't because it's a little bit embarrassing, but hey, people confess all sorts of things on their blogs.  So here goes: I have a secret fascination with the streets in D.C. that are named after states.  I have been actively trying to find them, and I know all sorts of interesting little facts about them.  Not to bore you, but here are some examples:
--All but two are Avenues.  Ohio Drive and California Street are the exceptions.
--Georgia Avenue used to be a little street in Southeast D.C. (which is now Potomac Avenue).  It was relocated to Northwest when a Congressman from Georgia lobbied for a more impressive street for Georgia.
--Florida Avenue used to be called Boundary Street because it was the northern boundary of the City of Washington back when the City and the rest of the District, Washington County, were distinct.

Not too long ago, I decided to document my search for the state streets by taking pictures of all of them.  (I told you it was weird . . . )  I obviously want to have a set of 50 when I'm all finished.  I've got about 10 already, most of which are pretty close to my house.  Tennessee was this morning's accomplishment.  Of the others, I know where most of the streets are; it's just a matter of being in the right place with a camera and traffic conditions being such that trying to get the picture won't cause an accident.

But for a few states, I don't know where the corresponding streets are.  If you know where I can find any of these, please let me know!
