William helped me dig out one of the fence posts down as deep as we could go without a post digger. After some time I was able to pull out the second rotten post but didn't dig much deeper. I began playing with how to install a post when the adjoining neighbour Dave came out to help. He revealed that he'd installed many posts on his brother's ranch and knew the technique. We put in both posts and then the panels before exhaustion took over. Job is 80% done. Cost so far: $30.
