We were hiking about 10 minutes in from the road on Old Loggers Trail when we heard what sounded like a baby screaming/crying loudly. It was a continuous screaming that we heard for about 5-7 seconds before these two creatures ran through the woods about 35 yards from us. Couldn't get a good picture or even a great look because they were running about as a fast as a dog and there were a lot of trees. They looked to be dark brown, and around knee height with a tail at least a foot in length. Their running was not very graceful (like a cat would be), more lumbering with thick legs. They were in sight for about 10 seconds before disappearing through the woods again, but the total time they were screaming was about 25 seconds non-stop. We went back and were able to find a number of tracks where we had seen them running.
This description is from both me and my boyfriend. I saw them through the viewfinder of my camera while my boyfriend had a clearer view.
