Tower of Goats

Via BoingBoing:

Jim Leftwich says:

"I'm thinking the next step beyond raising chickens in the backyard is to have your own Goat Tower!

"Currently there are only three Goat Towers in the world (which I think you'll agree is not nearly enough!). The original Goat Tower was built in 1981 by Charles Back at the Fairview Wine and Cheese Estate in Paarl, South Africa. The estate has 750 Saanen goats and some of these are allowed access to the tower."
