This is my second swipe through The Castro to hit all the streets.
I'm not exactly sure of the technical boundaries of this neighborhood, but I think Delores Street is the eastern edge.
Speaking of Delores, I heard on Twitter that a huge census sheet had been erected in Delores Park. I ruled it a 'must see' and planned my walk around it. Ta-dah! It's a huge inflatable census! Our tax dollars at work!!
Back to focusing on the walk. I think Market Street is the northern boundary of the Castro, but not sure. You know what I AM sure about? How awesome this sign is.
I guess the best way to tell when you are in the Castro or not is to look for the rainbow banners.
