Thanks for the feedback to my earlier post and inquiry. Your thoughtful replies were very helpful. Please compare rural bicycle roads and routes in Rutherford County with those in Williamson County. (Variables include traffic, condition of country roads, roadkill, courtesy of motor vehicle drivers, etc.)

Murfreesboro, Rutherford, Cannon County all the way. It really depends on what type of residence you want. Riding is great in all 3 counties. Obviously, further away from town has less traffic. Perhaps rent & buy after you've explored.
