When will Big Bob sink?

That's a question that could win you $500 in Osakis Chamber Bucks.

Big Bob is a giant bobber on Lake Osakis, just out from the public access.

He will stay there until warm weather melts enough ice for the bobber to fall and become fully submerged.

The Osakis Chamber of Commerce is sponsoring the first-ever contest. To play, buy a $5 raffle ticket, available at local businesses, and fill out the entry form with the date, hour and minute you think that Big Bob will sink.

The closest guess to the actual sinking time, as determined by the chamber, will win the $500 in Chamber Bucks. A $100 Chamber Bucks winner will also be drawn at random from all the entries.
