Indiana towns of 2,500+ (593)Ahead of 75%
Few Indiana towns conserve much land (a typical one, 2%; the U.S., 4%), so Greenfield’s 3% is ahead of 69% of Indiana towns, while its trails per square mile lead 68% of them.
How sure. Graded on any three of the four inputs instead, the letter would range from B− to B. 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.
