Tennessee towns of 2,500+ (177)Ahead of 98%
Few Tennessee towns conserve much land (a typical one, 1%; the U.S., 4%), so Oak Hill’s 22% is ahead of 97% of Tennessee towns, while its trails per square mile lead 82% of them.
How sure. Graded on any three of the four inputs instead, the letter would range from B+ to A. Trails and many small parks come from OpenStreetMap, mapped by volunteers, so coverage varies from town to town; the half mile is a straight line from each census block, so a river or highway in the way isn’t counted against it.
