Good to see a Ohio based thread on local trails! Have been on every trail mentioned over the past few years, well couple of decades anyway.
Many great places to ride here. Park in Xenia and ride to Columbus. Springfield and ride to Dayton. Columbus to London. Heck my son and I have even left Columbus and rode to Cincy mostly on trails.
I'm fortunate to have actually have MUP in my backyard and the Ohio to Erie trail about half mile away!
