A friend of mine is giving me 15 posts and the related rails of 3-rail split rail fence. I know this isn't rocket science, but I have a couple of general questions to ask the group.
I'd like to use it to border my driveway and was wondering how far off the gravel drive to put it. Part of me is saying put it right on the edge so I only need to worry about the grass on one side of it and part of me is saying it should be away from the edge by ? so many feet to allow for plowing.
Also, I was told that 3-rail is hard to come by in our area. Since I know I'll need to buy more to do the entire job I was wondering if I should cut the top of the posts off and turn it into 2-rail and have the extra rails left over for future use.
I would really appreciate any rule of thumb advice on this project, even as far as installing it is concerned.

Thanks
