This is our third summer here in West Michigan and I finally bought a marine radio to keep on the boat can anyone tell me which channels most of the marines in the area monitor? We are out of the Wharf marina in Grand Haven and run between Muskegon and Saugatuck. Also is there an automated radio check for the area? I checked the Sea Tow site and the nearest one I could see on their map was Milwaukee.
