This morning I rented a kayak and paid to have it shuttled to the Turner River where I spent 6 hours on the water. During that time I encountered two other paddlers and a half dozen alligators ( a good ratio in my opinion). Paddling down stream I encountered two very long mangrove tunnels varying in width from 1.5 to 4 boat widths. The mangrove roots were so densely spaced that they would have made an effective set of prison bars. The upper branches formed an equally dense canopy creating a true living tunnel. There was insufficient clearance to paddle and it was far easier to simply grab the branches and pull myself through the tunnels.
