It looks like the last post was over a year ago.
Is anyone else tracking any of this information?
Perhaps, priorities changed or they are advocating the improvement of the parks in a different manner. Have you tried to use the "contact us" link on the blog?
I don't think there was ever anything on there that detailed. Maybe the city would have something in the Special Collections department in the main public library.

To be frank, the blog was never really my main plan. My original plan was a resource site with historical data, photos, postcards, future plans, and on going developments (not electrical plans). I had a good start on it but ended up losing by way of an ISP change, and I just never got it re-hosted.
But thanks for your sudden and probing interest, and asking as though I am not a regular poster on here.
