Here's a graphic of ice-out guesses, showing how many people guessed each day. It will be interesting to see how close the wisdom of crowds comes to the actual date. Interestingly, as of a few days ago, April 11'th was the winning date with 16 guesses, but after the contest closed, the most guessed date is March 22, with 25 guesses. Lots of late entries came in with earlier guesses.
