The Charles Russell Obed River Preserve, located 3 miles off I-40 exit 320, is a conservation easement established through the Tennessee Parks and Greenways Foundation. The Preserve is not open to the public at this time, but butterfly lovers who would like to try to see the Dianas may contact me off list for directions and to arrange a time to visit.
