Join FLPG and SOFO on a leisurely-paced hike through open-field trails. The Pink Moon name comes from the herb moss pink, or wild ground phlox, which is one of the earliest widespread flowers of the spring. Other names for this month’s celestial body include the Full Sprouting Grass Moon, the Egg Moon, and among coastal tribes the Full Fish Moon, because this was the time that the shad swam upstream to spawn. Hikes are limited to 25 participants. To register email greenbeltnews@aol.com.
