Alot of land around here was cleaned up by being "goated out". When I was a kid, people would cut the trees for wood in the winter and turn brush goats in to eat the sprouts down and kill them out. I tried goat once.
Kind of like the two guys talking and one said, I tried goat once, didn't like it and never again. Then he said, I tried sheep once, didn't like it, so never again. Then he said, I tried llama once, didn't like it, so never again. He saw a car coming down the road, and said I better get ready to go, here comes my son. The other guy thought for a moment and said, Your ONLY son, no doubt!
