FAIRBANKS -- The tripod is up on the Tanana River.
When the ice goes out and the tripod falls, someone is going to be a lot richer.
The Fairbanks Daily News-Miner reports officials in Nenana on Sunday erected the structure on the ice in preparation for the Nenana Ice Classic.
For $2.50 a guess, ticket buyers try to predict when the river ice will start to go out. The jackpot is traditionally about $300,000. This has been a tradition since 1917, and records show the ice goes out anywhere between April 20 and May 20.
