Amazingly, Petanque is being played at the Campus Martius Park (in Detroit off Woodware, near Compuware) on Saturdays, (between 9am-3pm).
And Joe and I didn't know ANYTHING about it until recently! We're going to see who is running this (every) Saturday event and congratulate them and join in a few games.
Strange but true, sometimes Petanque DOES exist in Michigan without the help of Joe and Jeff.
