Thanks BZH. An interesting perspective. I will try to avoid dirt bikes and co-exist with the equine friends. While looking for gear and answers to my endless questions today, I happened to run into a guy named Chad at the Moosejaw store in Kansas City. He grew up in Tennessee and is very familiar with the Smokies. He pretty much is ok with using the horse trails too. He said many times their is a parrallel foot trail and you are just sharing a route between campsites. Thank you for your input and advice.
