Ned Skeldon Stadium was the home of the Toledo Mud Hens from 1965-2002. I drove through the Maumee area recently, and had a few minutes to swing by and take some quick pictures.
I wasn't able to get inside, but I did get some photos from around it.
I asked someone near the park about getting in. I was told that a very nice guy keeps the place up, and does a good job. Schools still play there games on the field. I looked for the grounds keeper, but I could not find him.
