Ugh. I feel your pain. Reminds me of when we lived in Michigan years ago. The neighbors' cattle got out periodically or all the time; whichever came first. They came over and tromped thru our planted garden so many times. My mom would go in the house and cry. The farmer who owned the cattle was a big, jolly sort of a guy. He would just say, if they come over again, you just shoot 'em. Of course, we never did. (and I'm talking a large number of cows)!
