My dove field is about 4 acres. I'd like to put a fake powerline right down the center. A few weeks ago I bought a 3 point post hole digger at an estate auction. I've never used one before. Are there any tips or advice on setting up the poles? Do I need guy wires or some other support to keep them up? For lumber, I'm using some irregular 8 foot pieces of 3x4 railroad track type of lumber.
