this work? i could have drawn it much better too
The older version of google earth has an aerial photograph of the gardens from 1995. You can (or at least used to be able to) fade in and out of the 1995 photo and current day. When you do that, you can see that the alley/rows of the gardens has changed pretty dramatically over time.
I’m not trying to discount your observation, I’m just trying to share something that I considered a road block in my own Boston search.
I truly hope this leads to some discovery.
