You are searching for a blue topped tupperware container.
You are walking on the Marjory Harris Carr Cross Florida Greenway - Silver Springs Connector Trail. The trail runs from the visitor center to the boat basin. This is a good trail but is sometimes muddy. This is real Florida, so be ready for ticks and mosquitos. I took several averages but be ready for some bounce. I will get you close. If you shoot better coordiantes please share in your log. All containers are tethered to some large or permanant structure. You are looking for one of the large towering oaks found along the trail.
