Used to live in Northern Virginia where our HOA would hire a goat herder to clean out the common grounds. I can vouch that they have a voracious appetite.
Goats eat poison ivy, which right there has great value.
A town near me hired a goat herd and the herder would move the electric fence every week or so as the goats denuded the landscape.
I made the mistake of touching the electric goat fence.
Once.
Goats are an ecological disaster. The Middle Easr is, at least in part, the arid place that is is due to the goat.
