M_Boats: M15 in Madison

Yesterday as I was driving in my hometown of Madison, WI, I saw to my surprise on Seminole Parkway an M15 parked on its trailer on the side of the road. My surprise was great enough that I stopped to take a look. (For many years I thought my M17, Seaweed, was the only M-boat around.) It seems it is a boat from California, pulled by a car registered in Colorado. I was wondering if it's anyone from the list. It would be fun to go sailing with two Montys together! Andrei.
