I've grown up and still live in the metro Detroit area. I would say they are still very active, I've heard they have a stake in Tringale sanitation and usually hang around a privately owned clubhouse on Gratiot called Danny Boys Social club. Or if you just want to see some of them hanging around and are in the area you can try Bacco's Restaurant on northwestern or Luciano's on 17 and Garfield in Clinton Township, if you really want to learn more about them you can pick up a book by the name of Motor City Mafia , very informative book written by Scott Burnstein who as far as I can tell can answer any questions you have about them.
Scott posts often over on the Real Deal forum. He's given a lot of great info on the Detroit mob, both past and present, but I personally think he tends to overstate the size and scope of the Detroit family at present. Just my opinion.
