Awesome! Many tracks will allow cyclists to ride them, and a lot of rides begin or end on NASCAR tracks.
DH wants us to do a multi day tour, and Land Between the Lakes is one place he wants to camp and do some trail riding. One day he wants to ride across America, but not sure I'm up for that much. We do have a little trailer we can use, but don't think he would let me put a machine in it.
Have fun!
Have a great time and post pictures when you can.
