Deja Vu Yet AGAIN

Just as I thought the sailing sled topic had run it’s course this little photo was sent in from WI by Deb at the Four Lakes Ice Yacht Club.

This is impressive- I get the dogs, the sails make sense, but what’s with the little wheel in back? Does it measure distance? Speed? Both?

Anyone know where, what and when? Leave a comment if you do-

Think Ice! T
