There is a big event at Bundy Hill every year. Look for the "Trike Circus" in the Events and Rides section of the forum for more info (nothing yet for the 2014 event, but keep a look out for it). You'll also see random posting of guys heading out there during the warmer months, with open invites for anyone to join them. It is a nice place to ride, but can be very muddy if the weather has been wet.

It isn't too bad of a drive from Toledo.
