I overheard rumors at the OMBC series finale this weekend that they will run the series again, and that the course will be more "cyclocross like" (real barriers, less singletrack etc.) but I didn't hear any mention of dates etc.
I also heard something about a MTB race on the 19th of November (the Turkey Race).
Apparently they're expecting the news to spread by word of mouth, because the 'knob website hasn't been updated in a loooooong time.
I'll ask around at the Orrville cross race this weekend since I bet a lot of those guys are local to the 'knob.
