Prior to the kung-flu myself and the OP would make the journey every year. Dayton had its charms, and yes, I was there for 'Crapapocalypse'. Some of the key pieces of the station came from there, including both my previous linear amps. Xenia is a nice venue, sans the stench of a thousand horses from the stables. The down side is unlike Dayton, most of the flea market is on grass. If (when) it rains, it's mud city. Speaking of which the weather is always unpredictable. I've seen wind, sun, thunder, and sleet over the last decade.
I wish I was there. Fun stuff to look at, but with the price of gas and the work schedule what it is, I just couldn't make it this year. Maybe next one.
