I am using a portable arbor on a bluff and there can be wind from the Atlantic. How are you tethering down your arbors? I was going to run a cord from each corner pole down to a hook (lack of better word) that is screwed into the ground. These hooks will be placed about 2-3' out from the arbor's footprint. I would like to hide the cord yet not hide it too much because I don't want any of the wedding party tripping over it. Any suggestions?
