Bainbridge is roughly 20-25 minutes W of Chillicothe on Route 50.
Meeting Place: Marathon Gas Station on Route 50 about a mile past Paint Valley HS and the Seip Mound on the right. There's a vacant store and parking lot adjacent that should serve nicely for parking. Ride start is 8:30am and it will be a great one.

COP has the Steve Barbour Memorial ride with start times from 7:30-9:00am at the Grizzell Middles School in Dublin. It is $35 for a day of registration with marked roads and a map at the start. Fairly flat route.
Lastly, there is a Gus Cook production, from in FRONT of Starbucks in New Albany at 8:00am. The pace is spirited conversational. I am pretty sure there will be a large turnout and a broad range of fitness levels. If you are wondering who will be there, well Gus, probably Peggy, me, Flyin Tuna, Granville John, Dirty Dan and many, many others. The route is: https://ridewithgps.com/routes/15982891
