That's the Mo Research Park extension trailhead, right before the St. Charles trailhead pic--my "home" trailhead! We regularly ride the area from St. Charles to Defiance (ice cream stop!) Glad you enjoyed my home state of Missouri. We're still trying to do the west end from Jeff City. Maybe this year. I'll do it end to end at least once :-)

I always wonder how far people have ridden when we see them on our end. We passed the Bike & Build team last year. The trail is also mentioned in Kurmaskie's book, "Momentum."
