Just off of Old Hickory Rd, in Brentwood, is the Percy Warner horse park. On any given weekend you'll see 5 - 20 trailers there, during the week you will darn near have the place to yourself. It's a great park for a 1 - 3 hour ride. They have a few different trails that are clearly marked with red, yellow and blue (?) arrows and go from 3 - 12 miles. It's a great place to see other riders. It's a park, so I wouldn't recommend it for aggressive rides, but it's a nice place for a leisurely ride or to take a lunch and eat at the many picnic tables along the way. You'll probably also see hikers, although some trails are for horses only. It's the kind of place where you'll see riders of all ages and skills, lots of english and dressage riders. It's a place probably more suited to a helmet than a cowboy hat and spurs ;-), but we wear our cowboy hats anyway and enjoy the wide, well cared for trails.
