Ah, the beauty of a brownstone, one of those three to five story residential buildings so prominent in the residential neighborhoods of Brooklyn, Greenwich Village, and other environs.
So: what's a "Brownstone"? Good question, relevant as you consider what to submit.
Dictionary.com sez:
"A house built or faced with brownish-red sandstone."
And Wikipedia sez:
"In New York City a brownstone is understood to be a rowhouse clad in brownstone."
Note that I am making a sacrifice for the greater good, since I live in a limestone. No home shots from me in this pool.
