Mike, my personal favorites are the outer sites on the end of the loop which are 15, 17, 18, 20, 22, 23, but others may have a different opinion. TV reception isn't the best so if you plan on any inside time you may want to bring some movies or Dish. The woods are thick so a dish is tricky to setup. If you like to hike be sure to look at the ruins of the old Mill, "Wilhoite Mill Trail". I love history myself, it's a short walk depending on where you start.
