The feeling of being watched in Lake County, Florida

To this day I cannot honestly say this was a sighting or not. I will leave that conclusion to those with more knowledge of Sasquatch behavior to decide. At the time my knowledge of Sasquatch, Bigfoot or the skunk-ape was limited only to what I had seen on t.v. or read in the papers rarely. In fact, I was under the belief that the Patterson tape had been debunked and bigfoot was probably a myth. It was a clear March day and I being off from work decided to take a day hike in Rock Springs State Park. The park is not heavily used I think mainly because its reputation for a healthy black bear population keeps city dwelling day hikers well clear of it. I have hiked many time in bear country and the idea of a bear encounter wasn't a worry. I decided on a loop trail approximately 2 miles in length basically as a warm up then planned on hiking different parts of the area. The woods very basically slash pine and palmetto with clear scrub meadow and shallow swamp areas a little deeper in. A well defined trail led through the palmetto. About 1/2 a mile in I noticed the woods had become very quiet and I began to feel as if I was not alone but being watched. In the middle of the trail I came upon a very large of very fresh scat. It was directly centered in the middle of the trail and the stools were incredibly large and long approximately 3 having lengths of between 9 and 11 inches. This was not bear scat as I have seen piles of that before and never saw continuous lengths of stool such as this. Again feeling that I was not alone I developed the strangest feeling that this was there for me to find and that it was meant as a warning not to go further. The fear I felt became almost irrational but I had no doubt I should turn around and leave this area. I have spent many hours in the woods but had never felt this type of flight or fight feeling. I now know that primates have used scat to mark territory and warn others away. Could this have been a warning left by a primate to me? I honestly don't know.
