By the way this guy has been a dive shop manager for over 20 years. He told me the other day that he new the location of a sunken jet ski that he was going to recover as soon as the lake went down 20 or 30 feet. It's currently in 180 feet of water, but because the arm of the lake it's in has really steep sides it should only be about 80 or 90 feet deep after the level drops. I had him repeat this to make sure he didn't just fumble his words. Then I brought a friend in and got him to tell the same story. It never changed. Many many more..
