I was just now looking at that same exact fence. Im assuming you bought a few lengths of fence as your area looks pretty big. Hmmm...Going to take pictures now. But from the video I watched it shows it having tent spike to hold the fence down on uneven terrain like mine so maybe it will work.
I actually only had to buy two but I butt it up to the privacy fence and I didn't need to run it there, so yes it's a big area.
