As we approached the lock, these boats were waiting ahead of us to get in, tied to the “dolphin pilings”. Note the green light allowing us to enter the lock. While at the lock, a new Visitor’s center employee, Sarah, was taking an introductory tour. We offered to take her to the Visitor’s Center on our boat, and her supervisor agreed. Boats can stop mid-Swamp at the Visitor’s Center and tie up overnight. When we arrived, there were already a few boats there, so we rafted to the outside of a sailboat, Arapesh from Canada. Sunday School, fellow looper, was also there.
