Hey, Danny. I suspect your better bet for information would be on Facebook - there's a group for Nashville Disc Golf and another for Williamson County Disc Golf. Posting there should get you more eyes on them. I still wander by here every now and then, but as you can tell, there's more tumbleweeds flying this site than discs.
Also, I have three boys (12, 10, 9) who play with us on a regular basis. Come on out some Sunday afternoon at 2!
