Hi Paul,
I have very hard clay. However, it's jsut as bad as soft soil as it
liquifies as it gets wet. My goal is to keep the post in place during
these conditions. We live in an area of high winds and that usually
accompanies rain so I can see how this problem got started.
I plan to do about 3 posts per weekend over the Summer. I'll take a
look at your post. Thanks for the reply.
