Jobbie Nooner

Jobbie Nooner is the 2nd largest boat party in the Midwest, after The Raft Off at nearby Muscamoot Bay, and one of the largest boat parties in America. It takes place around Gull Island in Lake Saint Clair, Michigan.
According to co-creator Jack Campbell, "The very first Jobbie Nooner occurred Friday, June 28th, 1974." 
Auto workers who called themselves "Jobbies", would take the last Friday in June off work to party at Gull Island (Lake St. Clair, Michigan). The event was originally timed to coincide with the birthday of Lee Wagner, the event's other co-creator, but eventually grew to become a bigger celebration.
The party now occurs twice a year. Jobbie Nooner is the last Friday in June and Jobbie Nooner Two is the first Saturday after Labor Day.
