Report 26767: Camper sees large bipedal creature leave her camp heading to the river.

Several of us old hippies meet once a year in October at Tishomingo, Ok to camp and enjoy each other.  This October (the first week-end) we met as usual at the Tishomingo state park.  There were 15 of us at the campsite on Saturday night.  It was around 9:30 pm when I was leaving the burning embers and people behind me to walk to my tent alone.  When I got about halfway to the tent, someone ran across in front of me in front (close to) the tent.  I knew all of the campers were at the site and most of them cannot run.  I don't drink or do drugs and so I stopped for a moment and thought about who it could have been.  My tent was facing the Blue River.  I stopped, turned around and decided to try to get back to all of the people.  When I reached them, I asked for someone to walk me back to the tent with a flashlight.  Two of my friends, males, made fun of the sighting I informed them about and told me it was probably a deer.  Deer run on four legs!  Then they told me it was probably one of the brown bears.  Brown bears can't run with the stride of a man and they aren't that tall (around 6' or more).  I got in my tent and loaded my gun and slept with it under my pillow (my hands making sure the steel was touching the gun all night long).  I had two small dogs with me that I felt would alert me to any other encounters with something outside of the tent.  I know I saw  the stride of a man as he ran from West to East.  There is a large light towards the South end of the camping area that allowed me to see the creature.  I am positive everyone was at the campsite when the "Thing" was seen running.  When I told my girlfriend in Florida about the sighting she said I ought to tell someone and therefore I am telling you (whoever you are.
