09-Apr-2011 -- Wow - this was one of the most interesting confluence points I've visited in a while: In the middle of a swamp.
I decided to make a short detour from the Natchez Trace Parkway to visit this confluence point nearby. Looking at satellite images beforehand, I figured that I could probably avoid much of the swampy terrain by approaching from the paved road to the east, starting at [34.001265,-88.993341], rather than from the much closer farm road to the west. And it's true: After hiking through a pasture (with cows), then along a farm road; then through vegetation, I was able to get within 100 meters - close enough for a successful visit - without venturing into the swamp. But of course, that wasn't good enough for me; I had to get "all zeros", which required walking out into the swamp.
A note to future visitors: Be sure to wear long trousers. The vegetation on the perimeter of the swamp is very thorny. You'll need long trousers to protect your legs as you approach the swamp, even though you'll get the bottom of them wet later on, as you enter the swamp.
