The Janesville Boys and Girls Club may have a windfall donation, but not a lot of time to cash in. Board Treasurer Tyler Mosley says a donor has offered four tickets to the Superbowl valued at $12 thousand each. Mosley is hoping for a top bid of $40 thousand by Thursday afternoon. Mosley says he’s doing as many media interviews as possible in the New England, Philadelphia, and Minneapolis areas. The tickets are in the 200 level club seats between the 20-yard lines on the visitor side.
