An hour ago I went out to feed Casey, and she wasn't in her pasture. I freaked a little bit, but then calmed down. I looked at the fence, and the gate had popped open, literally. I make small movable electric pens around our lawn to have her 'mow' it, and I tied the end of the electric fence around the fence post that I use as a gate, and it came undone! I figured, okay, she didn't go out the back gate, there is a fence blocking that. I doubt she left down the road, she wouldn't go over the metal bridge, to scary, and I have only brought her over it 1-2 times a couple years to. I walked out front to the house, and Casey nickered at me. She was standing right there, next to the fence!
