Swingset at the Lake

Early fall 1970. Myself and my brothers and two eldest cousins on the swingset at my grandmother's resort, on Thayer Lake between the villages of Alden and Clam Lake, Michigan.

If I remember correctly, the cottage on the left was named "Doug" after my older brother (in the seat with me), and the one on the right is "Debbie", named after my cousin (on the leftmost swing).
