Welcome to the Haysville Shelter. Clearly the park ran out of local people to name shelters after, so other names were used. I'm assuming that this shelter was named after the nearby borough of Haysville...
This shelter is not used anymore and it is not a busy place, although it is a good location. The other nearby shelters have all received recent makeovers in the form of new roofs, etc., but it looks like this shelter may just fade into obscurity...
Please replace as found. BYOP.
Congrats to sgram33 for the FTF!
