Probably not a good idea to take a shot at swimming across the Mississippi River. Three people found that out this morning. They were lucky because Randy Ziebell happened to see the swimmers struggling in the river while he was at his boathouse on Pettibone Island. Ziebell got out his boat and rescued Brook Gast, Dylan Low and Amanda Halderson. The LaCrosse Fire Department thanks Randy for his fast response and warns everyone that they need to be careful whenever they're swimming in the river and that the main channel is difficult to navigate for long distances due to a very strong current.
