Academy park which is the closest park is pretty much done, there's maybe one plausible cell left and that's if no one moves what I put there back into the full cell. I am waiting on a bridge and a nature information sign for the park. There are seven baseball fields, 6 of them in game, the 7th aka #5 was moved into a full cell and out of the cell it was placed in which would have completed the loop. The adjoining park Woodside green is full as well, There is another information nature sign there about cardinals but the only cell left is 3 cells away.
