Brooklyn makes some good beers.
There is a microbrewery right down the street from my house:
Flying Dog Brewery - American Ale Craft Beer Brand Store Online
They brew Flying Dog and Wild Goose beers, both of which are very good.
Dogfish Head
Dogfish Head out of Delaware makes great beer
There a few brewpubs here in Frederick MD that make pretty decent beer. Gordon Biersch has some decent beer too.
