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.
