How did Zoo-De-Mack get started?

Many years ago, we had brand new mountain bikes and an old memory of a picturesque road from Harbor Springs to Mackinaw City.  We called some friends, talked eight of them into riding it, and the next thing you know we found ourselves on Mackinac Island with grins from ear to ear. The next year we wrote a flyer and had 80 participants, and have since watched it grow to to 2000 annually and have had up to 4000 participants.
