It's quiz time!

Pardon me for asking, but do you know where in Carroll Gardens this is?
I must have walked by this thing a thousand times and never noticed it, though it is not hard to spot.
Is it just me? Have you noticed this weather vane before?
Do you know where it is?
If you do, leave a comment or shoot me an email. You may just be a winner in Pardon Me For Asking's first "Where In Carroll Gardens' Is This" quiz.
