The Gallagher Smart Fence
includes 4 strands and 10 posts (5 of which also include guy wires for corners) and is 328 feet long.
It is less expensive per foot than nets and is much less bulky to store. It also does a great job of weaned lambs on the right side of their fence.
It's easy to join one smart fence to another and so far i'd call it a WIN. We'll see how it holds up, but if it does well over then next year or so I think we'll be replacing the nets with Smart Fence's as they wear out.
