Report 69008: Sighting by motorist in thick river bottom 75 miles northeast of Memphis

I was driving on Highway 104 between Trenton Tn and Dyersburg Tn . We were headed home. There is a large wooded area as you are in Dyer county and Gibson county . I look to my left glancing at the woods just before the river. I did a double take. Told my wife and my son, "You wont believe what I just saw!" I estimate it to be about 7-8 ft in high. I didn't stop because a vehicle was behind me. I have went over it several times in my head to what I saw. There are no bear here and it wasn't a human or anything else I have seen. That's my sighting.
