Hi. I’m new to this site, but I’m an old pro at Missouri’s trails and parks. There is an extremely useful website that offers a variety of guidebooks, from the Katy to Trail to mountain biking and hiking trails to plain ‘ol cycling trails. pebblepublishing.com You can have books shipped within a few days. The Katy Trail Guidebook is absolutely thorough! I hope that’s helpful to some of you fellow bikers.
