There you go! Take some pictures and keep us updated.Today I got a 12 foot by 4 by 4. I will take a measurement and cut in the middle cus I want 2 posts. As well I got plastic mounts for the bottom.
Don't want the salt to rot the bottoms and keep them from sliding. I think it is around 6 feet 4 high. I think I can use exterior 2 by 4's to build it up a bit at the top or base but not both. If not something pressure treated.
