APS,
The photo that you posted is good old Jobbie Nooner on Gull Island.
It’s known as the Mardi Gras of the Midwest and the title is well earned. With thousands of revelers congregating on Gull Island, Lake St. Clair every year, this wild event is a Detroit favorite.
If you enjoy rafting, then take a trip to this one:
