Roughly mark the position of the posts for the ends and any bends of your fence (1, 2 and 3 shown on figure).
You now have the straight runs roughly identified. Look at the slope of the ground and mark any point where the angle of the ground
level changes significantly (4 on figure). These are the main points where there MUST be posts.
- 1 and 3 being 'end' straining posts.
- 2 being an 'intermediate' straining post.
- 4 being a 'standard' post.
