Anything is possible Lucasi. I don't think anyone here has first hand insider's knowledge.
But even very very broadly defined Metro Detroit (the city proper and several of the outlying counties) only has somewhere between 4 and 5 million people. NYC alone has over 8 million. That's almost as many people as the entire State of Michigan. So I just find it hard to believe that such a relatively small area with a shrinking and shifting economy would be able to support such a large active Family of 100 made men with 2 to 5 times that number of associates. Most of the information with which I'm familiar seems to indicate a very small hub of active family members with relatively modest businesses/illegal activities by NY standards. 30~40 guys seems more likely.
