I want to redo my pasture fences in a more horse friendly fence than the barb that came with the place. I plan to build a post and rail fence because I can do that by myself a section at a time as the money is available. I have looked at lots of them as I have driven around but am confused about the corners. I want the rails on the inside for when the horses lean on the fence but this creates a bit of a problem at the corners. What are some different methods for dealing with this. Right now I am leaning towards having 2 posts close to the end of each fence run and just extending the rails a little past the end post to where they will meet. I built a large 3 rail arena when we first moved here, the project isn't that bad once the holes are done. But my oval arena, obviously, doesn't have any right angle corners. What to do, what to do?
