Yo I am building a rail for some jibs in my backyard... Any suggestions? I am thinking bout buying like a 4" wide rail that is 10' long. Or I could buy two 2"x10' rails and make a shotgun rail. I have no idea which I should go with. Also how should I don't really want to have to get wood to put it on supports, could I just do like 1 plank at the end of the rail so that it goes up at the end?
