This cache is in an ammo case, it contains lighters, pens, knives, PEZ, and other 'stuff,' it also contains my trademark POGS.
As stated, you will need at least and SUV and knee high boots, but a lifted 4x4 such as a Wrangler or Cherokee would be best. To keep this form being impossible I will tell you you will not have to go past one gate or tresspassing sign, the area is open to all and perfectly legal. Find your way to the FPL service road that runs north south, you will find a trail that runs south. Follow your GPS' nose and jump on more trails. You will come to an area with 1.5' of water or so, cross with caution and take the trail in the direction of the coordinates.
From there you will be pointed to an area that looks like a lake of white mud, be careful, its deep and slippery, only drive it if you have 2 vehicles and recovery gear. Near a naturaly formed canopy you will find the cache. Then you will know why its called 'Horsefly Mud Flats.'
