Just grasshoppers. We no longer run any animals in our pastures, and have torn down much of the cross fencing. The perimeter fence is all still intact but the gates are either off the hinges or propped open. We mow the fields about twice per year to keep the Canadian thistle under control, but otherwise let the pasture grass grow. I especially like when it goes to seed, so pretty in the wind.
I forgot, I do also have two Cecile Brunner climbers on the driveway fence (5 strand barb) that runs perpendicular to this fence. I babysat the mother plant twice when my sister-in-law was between homes and ended up with a rooting each time. She originally brought a piece of it from her childhood home in Oregon. I love when a plant has a history.
