The Macomb County Sheriff is telling boaters to have a good, but safe time at today's annual Jobbie Nooner.
Deputies are on patrol on the water looking for violations of the law.
In addition to officers from the Macomb County Sheriff's Department, officers from the St. Clair County Marine Patrol Unit, the Border Patrol and the U.S. Coast Guard are on the water to make sure things don't get out of hand.
Patrols will focus on making sure boaters are not operating their vessels while intoxicated.
Thousands of people attend Jobbie Nooner annually, docking off Gull Island in what has become known as the "Mardi Gras of the Midwest."
The event has also become a way for many to officially kick off summer.
