The building inspector came out today to inspect the holes. He came and went with quite a bit of stealth. My wife noticed something on our door when she returned from the store. It was an 'Approved' sticker.
Next step - pouring the footers. I rented a cement mixer for the weekend, big enough that is has to be towed behind my truck, just like the auger. Hopefully the weather will cooperate and I can get them done in one day.
