I live in Clay County, just Northeast of Liberty, and we have some great roads out here for cycling. Very little traffic, rolling hills with flats and descent climbing, with the country scenery. Nothing like riding through the rolling hills with open fields surrounding you with the a beautiful sunset.
Let me know if you have anymore questions. I posted some of our weekly rides on mapmyride.com, with the starting location of Excelsior Springs, MO.
