Bunny damage

It's a bunny buffet! Bunnies are enjoying my garden. My neighbors tell me that this year there are more than usual. I saw four adults in the back the other day. We know what happens when adult bunnies get together. The techniques I used in the woods don't work here. I gave a family member a haircut, and sprinkled the hair around. No matter! They bit through string that the peas were growing on.  I'm going to have to invest in a fence.
