Ron,
Go with the
GOATS !!!
From what you have been telling us you have what they need and you want to control.
"Basic goat nutrition is important, and adequate roughage is a vital factor in this equation. Weeds, grass, and hay can usually provide the necessary roughage requirement."
You'll have milk covered and will go with the BBQ they are know for. Hides aren't bad for boots,belts or hatbands.
While the rest are feasting on your yard you can shear them for sweaters for those cool morning in your Cobra.
Just don't let them sweet talk you when they start whispering
RRROOOONNNN.
BTW Have you gotten the Bark thing yet ???
