I noticed the PSP in the background too. I hadn't seen that since Viet Nam. You can put down a real nice runway real fast with that stuff. Ours had three holes across, the French stuff had five holes across.
It is really heavy, and it will really do a job on your fingers though. My hands ache just thinking about it.
This is a great run ! I have been looking for a run design all day - this is exactly what I would like to have too, love the sections.
I might need a trench and hardware cloth at the bottom though - i am terrified of predators getting into my coop (this includes random dogs roaming and coons)
