Watch out for the blacks!
That should keep some folks away.
Is your State an 'open range" state. Cattle, sheep, horses, llamma, mules, etc get to go anywhere they want in our county, and a few others here. If you want them kept out of your flower beds, you best build the dang fence yourself. And there are rules as to what type of fence even. 4-5 strand barb wire and/or substantial enough to keep cattle out.
I bet some folks will be really happy if they move on to their 5 acres of open range when the cows are off it, only to set up housekeeping and have the cows come back at greenup to eat all their posies. ( I know of instances of this happening on a friends ranch in AZ)
