The terrain portion was easily 5 star with it being out on the air boat to get to portions. With being there for the CITO and the difficulty of actually removing a lot of the items (old pots and pans being pulled out of the swamp water with tools by two people at one time, items near gator nests, getting people to brave doing these things near the gators), I would rate the difficulty as a 5 star. I believe that any cache that requires tools increases the difficulty. At an event like this, the trash is the cache, and it required tools to get to a lot of items that were submerged or in areas that should not be reached into due to the dangers in the area. With all of that being said, ratings will always be debated. It was a great event, on real short notice, that helped an area that really needed it. The stars really didn't matter, it was all about helping a beautiful lake get back to what it should look like..........that and holding baby gators.
