I don't have horses so i cant speak to the tragedy waiting to happen. I use barb wire, 4 or 5 strands along the road, and the same on any creek crossings. other than that 2 hot strands will work. I have mine in a temporary pasture right now with just fiberglass posts and the rope type wire with the occasional t post for line post and corners. Some say it doesn't work that great, but the visibility of it along with it being easy to roll back up and move (i use drop cord reels from walmart) and the grown ones will stay in it with just one strand.
