There is a long history ice out in other parts of the USA.
My sister lives in Fairbanks, and Ice Out on the Chena River it is a big deal.. and big money!
They use a Tower and Clock that sounds similar to the Weirs Raft.
This story is about Tanana River.

Maybe we should bring back the raft idea! I would be fun... and someone could win some big bucks.
