Have never built a fence before, was sick of my neighbors dogs pooping in my yard. Searched this sub for ideas and this is what I came up with. 130ft long 6ft high used 5/4x6x8 treated for the slats. 6x6 at the corners and 4x4 for all the other posts. Lights took this project to the next level! Question for the pros, should I put a board every 4ft to keep from cupping? If so front or back? Open to any ideas to solve this. Thanks!
