My outdoor run is ruined. Not that they used anyways, there is 50+ inches of snow in it. But the snow just slid off the roof and crushed the fence. I wanted to rebuild anyways but the wife wouldn't let me last year. This time I am going to use 4x4's for the posts instead of those wimpy metal t-posts. that way I can build a roof over part of the run. Any advice on setting 4x4 posts in solid shale. It was a huge pain to just get the t-posts driven in the ground.
