These photos were taken with a disposable camera.  Part way through the day, the lanyard link broke with the camera "lost" on the ice.  Retracing my path for about 15 minutes, I was able to recover the camera along with a beer bottle.  Visibility was excellent. A simple leaf could be seen at some distance.  The previous year, one of our boaters lost his car keys on a larger lake.  They were never found.  I now keep mine on a colorful lanyard.

Taking photographs of iceboats speeding by at 50 mph while trying to control your own boat at 40 mph is difficult to say the least.
