 hosting a wedding reception crashed into a breakwater on Lake Superior. The St. Louis County Sheriff's Office says the boat hit the barrier in the Wisconsin entry about 11 p.m. Saturday night. One person on board had to be airlifted to St. Luke's Hospital for treatment but is expected to recover. More than 80 people were on board at the time of the crash, which remains under investigation. For those who don't know, a breakwater is a structure.
