Sounds like a sure fire way to turn your lush green property into a field of goats. If this was the 60's then Google might be one of the best companies to work for, but it's not, so have a shave you crusty old hippy wannabes, stop praying for legalization, and give the goats back.
Personally I have little time for goats, even novelty watch them out the window while at work ones... They are ill-tempered, smelly, and irritating poop machines.
Some things your lawnmower won't do...
1. eat cigarette buts then lick your face
2. take an dump on your nice clean lawn
3. try to goad you with their horns.
I would rather see an untidy, overgrown yard full of mini-beasts, birds, hedgehogs, squirrels etc etc.
