What kind of outdoors town is Mason Neck?

Read from the map. The page puts what stands out first.

Outdoors grade

How much outdoors does Mason Neck have?

On conserved land, trails, park land and how close residents live to a park, Mason Neck is ahead of 97% of U.S. towns. Conserved land holds the grade up; the share of residents near a park pulls it down.

A+
OutdoorsA character grade: shown, never part of Mason Neck’s overall grade.
All U.S. towns we grade (21,298)Ahead of 97%

Water is 31% of Mason Neck’s area (6 of 20 square miles), so every share here is of land; over land and water together, the conserved share would read 50%.

How sure. Graded on any three of the four inputs instead, the letter would range from A 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.
