I thought some of you might find this story interesting, so I'll take the chance and tell it even though some of you might find it long and boring.
My Grandfather was a wheat farmer in North Central Oklahoma. They lived near a creek and a bridge which crossed the road just about 100 yards from their house. When my Dad was about 10 years old (over 100 years ago), he said there was a group of Indians traveling by horseback, and stopped at the house and asked if they could camp down by the creek. Grandpa said "sure". Dad said they left about daylight, and he went down later to see where they had camped, and he noticed the remains of quite a few box turtles, which were picked clean, indicating that they were eaten.
He said they had a couple different campfires, and each one was "enclosed" with a ring of pegs driven into the ground very close to the fire. He surmised, from the looks of things, that they had scoured the area for box turtles and simply dumped them into the fire, and the pegs keeping them from getting out until they were cooked. It seemed bizarre when he told me this 60 or 70 years ago, and it still does sound bizarre, but ultimately very believable. He also experienced an Indian "raid" on his schoolhouse when he was in grade school (about 1915 or 16) when 4 or 5 drunk young bucks on horseback shot up the chimney with their 30-30's.
