We were contacted a couple years ago about having a group ride in conjunction with the '06 Superbowl in Detroit. With the new rail-trail opening next to Ford Field around that time, we thought it'd be a great publicity event.
We need a group ride leader who will contact the Superbowl committee and get our ride on their schedule. They'll also try to get a big group for the ride itself.
Email me if you're interested. I have all the contact information ready to go.
