I got a post hole auger from Home Depot and I was surprised on how well it performed in my hard clay. It is an 8 inch auger and zoom it went it right down. I am going to put a 4 x 4 post in the 3.5 foot deep hole to hang my hammock (no trees). I was thinking of using an 8 inch concrete form tube but do I really to? I will be using quick dry cement. I imagine that the 4x4 will be ~12 feet from the ground not sure. Thanks.
