We got up early and called the lock master, he said to come on in and tie up. We will ask more questions next time. He did not answer or radio calls for 10 minutes. When did answer he told us we would have to wait until he called for any other south bound vessels. Monarch was about to pull their anchor so we waited. It was about a 40 minute delay, no problem if the lock would just communicate. Next time we will ask a few questions so we can plan accordingly. We had a nice cruise down passing some beautiful white cliffs. The anchorage which is  about 7 miles above Demopolis Marina. Rattle Snake Bend is just of the Tenn-Tom, it is the original river alignment  before the locks were built. We had a very quite night and beautiful sunset.
