Reading it takes ten seconds: 52 dots, one per week. Solid teal is Apple Valley's swim season; the hollow teal run before it (April 6 to April 27) is when to open; the hollow amber run after is when to close, with November 1 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
