Announcement: Northeast Flag Referendum

I submitted Design 6. Here's an explanation from the thread:

The tricolor represents the three "biomes" of the Northeast, for lack of a better term: the green forests and farms of Vermont, Maine and Adirondack, the blue harbors of Massaconsett, Chesapeake and Lakeshore, and the concrete skylines of New York, Philadelphia and Pittsburgh (Appalachia). The upward slope symbolizes progress over time, and the labor of Northeasterners towards a better future. And in the middle is the state seal, obviously There's a finalized version of the flag that omits the seal.

I don't know anything about the other five flags.
