NoteFew parks or trails are mapped in Penryn. OpenStreetMap is mapped by volunteers and coverage varies from town to town, so a town with unmapped parks scores low on 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.
