There have been a lot of unusual venues chosen for playoff games this season. I assume there’s a lack of options as schools opt to not host. When the OHSAA keeps all ticket sales, the only real revenue is through concessions. Again assuming, but I doubt many schools make money or want their resources used, for such little gain.
As far as Piqua, this is one of the better venues around Dayton. It’s a great site to watch a game, even if a little out of the way for these two teams. I’m sure both fan bases will enjoy the venue.
