For those who don’t know, the Dayton Hamvention is THE hamfest. Held every year (although not this year) in May, it is the largest event of it’s kind in the country. The Hara Arena in Trotwood, Ohio, just outside of Dayton hosted Hamvention from 1964 until 2016, when it was announced that the arena would be closing and the event was moved to Xenia, Ohio. There was hope of rebuilding the venue, but extensive damaged received during the tornado outbreak on Memorial Day weekend 2019 put an end to that.
