Due to the move to a new venue, these maps and directions become pretty important. The new venue (the Greene County Expo) is in Xenia, OH, about 20 miles mostly east of the old venue in Dayton, OH. Instead of being located in a congested downtown area it is on a 2-lane sort of rural road. Below is a (clickable) map of the general area, with the thumbtack showing the Expo’s location about a mile north of Xenia’s center.
Zooming in a little bit to the Xenia area itself, we can see that once you leave one of the federal routes you transition to local roads. Your main goal is to get onto Fairgrounds Road.
From the west (Dayton area) you’d probably want to use US 35, turning left at the light at Trebein, then right at the light onto Dayton-Xenia, then left onto Hawkins Road (as you pass Kil-Kare speedway) then right on Fairgrounds.
If you are coming from some other direction you probably already have some familiarity with the area, but if you need help please ask Mr. Info.
Finally, here’s a closeup of the Expo itself. We’ll have signs by this point to direct you to the parking areas.
