50 + miles south of Fairbanks on the George Parks Highway is the town of Nenana, home to the Nenana Ice Classic.
Each year hundreds guess the exact month, day, hour and minute the ice in the Nenana River will break as the Spring thaw or 'Breakup' unfolds.
The payoff getting the moment right is nothing to sneeze at: the prize has continued to grow and the 2011 windfall was spilit between 22 winners - dividing a whopping $338,000 USD. (the ice officially broke on May 4th, at 4.24 PM)
You do have to be physically in Alaska to actually buy a ticket, and if you are between February 1st and April 5th 2012, click to this site to find the nearest location to buy your ticket:
