Carole Brush, former Eastern Trail Alliance executive director, leads a group of about 15 people each month through the Scarborough Marsh portion of the trail. The group is able to see the full moon clearly and learn about the area and trail history. After a hiatus, the Eastern Trail Alliance offers walking events on full moon nights. The next walk is scheduled for 7 to 8:30 p.m. Monday, Sept. 20 and is limited to 20 participants.
