I am considered old, but we had a diaper club in the 60's, with about 10 guys in the Crestwood subdivision of Fort Wayne.
We used to run around the neighborhood wearing diapers. Got caught by mothers and girls. Paschal, Crabill, Gaff, etcetera.
NO disposable diapers, only cloth. We thought that no one else in the world was excited about wearing diapers. It took me another 20 years to
find out that there were other people who loved diapers. Hard times.
