Black Tank, Swimming, Nolan Returns

Well, I opened the black tank valve and it sounded like everything came out OK but I then drained the sink tank to make sure. Everything seemed to be OK and the monitor said the tanks were empty. Not so hard. Cain and I decided we would go to the creek and play in the water. We took the dogs and had a great time. Just before we left Nolan called and he was about 45 minutes away from home. When we returned from swimming, he was home and I sure was glad!
