On the Shores of Old Lake Erie

Here's the building that used to be Lorain High School. This is the view of the seam where the cafeteria meets the front left of the building. The cafeteria was added to the building in the '70's, I think.

Here's a closer view of the area. I don't know if these bike racks were ever used. They're in a weird and impractical area, really. Near the middle-top of the picture is a sign.

Here's the sign, as best I could capture it. The builders joined the cafeteria building to the original building without regard to the fallout shelter sign. Why didn't they just remove it?
