If you pay the $35 fee to Metro Parks, you can fly at the three airfields in Metro Parks (Warner Park in Bellevue, EN Peeler Park in Madison near the Cumberland River, and one near Percy Priest Lake in Antioch). No flights are allowed around Natchez Trace Parkway because it's designated as a National Park, even though it's one of the most beautiful roads in the area. I fly at my father-in-law's farm some, and around my house or other friends' houses that give me permission to practice.
