Texas towns of 2,500+ (642)Ahead of 61%
Few Texas towns conserve much land (a typical one, 2%; the U.S., 4%), so Leon Valley’s 4% is ahead of 71% of Texas towns, while its trails per square mile lead 55% 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.
