Pops around the corner

Today I ate lunch with my dad at Bill's Produce. If you combine Fannin Mart, Cindy's Catfish, and Mike's Trading Post, you get Bill's produce. I had meat loaf with tomato gravy, and boy howdy. The past two times I've eaten there with my dad, he has taken his pencil out of his shirt pocket and drawn on the table to explain a point. Today I asked about conventional foundations. I was just wondering why so many houses out in the country have them, and newer houses don't. He explained that concrete wasn't as available in the smaller towns, and a lot of times carpenters didn't know about setting the steel in the slabs, and the plumbing was easier to manage. Then he drew diagrams on the countertop.
