Guided by a biologist from a local university, I placed this GeoCache on an island in Mobile Bay's Tensaw Delta. What I soon realized is that the real treasure of this GeoCache is its location. I am certain that you will leave this place with a greater appreciation for these wetlands. In regards to difficulty, I give it a "3" because you have to use a boat, however it's a "4" if you consider that there are alligators and poisonous snakes around, and if you are not comfortable with your boating skills in the shallows of the bayou, don't even attempt this hunt. This cache is hidden in a place that protects it from floating away.

Obligatory list of potential dangers: heat exhaustion, wildlife encounters, falling out of your boat, drowning.
