Tile cuts at valleys

One and two-piece mission tiles have to be fastened but they are a completely different animal. (I imagine you are just pulling our chains with the pic) Shingles, shakes, and slates have to be fastened too. In the old old days, back in the old country, they used to fasten stone slates with little pegs driven into holes in them. The Union generals felt that way about Nathan Bedford Forrest, too. They couldn't peg him and he was always slipping away to give them a new headache.
