Several years ago I was pulling a boat across the ice below the Guttenberg Dam and went in just past the Bullnose. Had a life jacket on and was holding the rope so I stopped at eye level. The feeling of no bottom and all that current rushing out the hole past my ears is one that will stay with me for a very long time. Several people had just crossed ahead of me with no rope or life jackets. Guess I hit just the right or wrong spot.
