I'm sure the answers to a question like this will quickly identify the geographic distribution of the respondants.

49 degrees? Well, that's still a bit too warm for any good ice.

The water's still liquid on the broad lake, but the shallow bays have started to freeze. (Plus, we have had four feet of snow in the past couple weeks). Last time I was out sailing was around Thanksgiving, racing with the local J24 fleet. The air temp was right around freezing. Snow-capped peaks framed the background. Not a cloud in the sky. NW winds at 12-14 knots. It just doesn't get any better!
