We got the peanut butter fence up on the farm — Scott and Anya attached the metal strips, and I smeared the with peanut butter. Since they are connected to an electric fence line, the idea is that a deer will lick at the peanut butter (evidently something they really like) and get an unpleasant jolt. It’s a solar energizer, so not too unpleasant. But enough for them to think “I’m gonna go eat this other green leafy stuff!”.
