TIL how to brace fences for strong winds after working in coastal Carolina

I was on a fence job in South Carolina last spring. The ground was sandy and the wind came off the ocean hard. An older guy on the site showed me to put in kickers at a 45-degree angle from the post to the rail. We dug them in deep and poured concrete to hold them. This stops the whole line from swaying during storms. I have since done this on three other jobs near lakes and it works great. It is a small extra step that makes a big difference in durability.
