Keep your eyes open for motorcycles this weekend.   The annual "Spring Flood Run" makes the unofficial beginning of the motorcycle riding season in Minnesota.  Up to 30,000 riders are expected to cruise on both sides of the Mississippi River this weekend.  On the Minnesota side, most of the riders will cruise between the Twin Cities and Winona.

The Flood Run has been a charity event since the original 12 bikers from the Cities rode to Winona to help the city in its fight against the flooding river.  Money raised by the official sponsors is donated to Gillette Children's Hospital.
