Wyoming towns of 2,500+ (28)Ahead of 11%
Wyoming towns conserve more land than most (a typical one, 9%; the U.S., 4%), so Mills’ 39% is ahead of 96% of Wyoming towns, while its trails per square mile lead 0% of them.
How sure. Graded on any three of the four inputs instead, the letter would range from C− 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.
