just time to time, we go to a friends farm and have some fun. -----Oy-----Stump cows?
My brother has 116 acres in Missouri. In one of his pastures, if you get close to the ground and look across it, you can see where there are spots built up about a foot, and in an approx. sixteen foot circular shapes. He said that Indians would build up the inside of their teepees, and the mounds were still there. His barn was built with square hand made nails, so I assume it was true.
