Look behind both Jenkins and Spangler; the Shea light towers.
Look behind Altman and Koonce; light towers. But those aren't Shea. Up until a couple days ago, I assumed that these were two more Shea pictures. I don't know what made me look a little closer at them, but as I did I had one of those "Ah Ha" moments. The grandstands in the background on both are most definitely not Shea. And as soon as I saw the stands, I knew which park it was.
I'll post the answer tomorrow.
Go ahead and Name that Park!
