The Great Blue flew by, right down the center of the swamp.
Looking at Google Maps I found a large stream, more swamp, and finally an open pond past our usual trail. This explains why the Eagle passes that way too.
I don’t see a way to get there without walking through some deep swamp… not happening.
The old Drayton Plantation is a few miles over there. Maybe an exploration day this summer to look for a back way.
