I had read about fences like these being used by commercial goat-aided-brush-removal services in the USA (apparently there are goat herders down there who have contracts with places like national parks and highway maintenance departments) but had never seen one until one showed up at our local Buckerfield's feed store.
Easily installed, amazingly tangle-free, we hooked the goat barricade into my electric horse fencing and, voila - the goats were contained and happily set to work.
Goats are happy. Neighbours are happy. I am happy.
