I Google mapped it, but don't see a Stonewall Street... Do see a Prison Ave between 16th and 17th, and Charlotte and Church (more specifically between 16th and 17th, and State and Patterson Streets) Prison Ave is one block long, so make sense it's commemorating the location of the old prison.

I have Sensing's book, it's a great read! There are a couple of other books out about Champ that have come out since, but haven't have a chance to read them, yet.

Thanks for you help!
