Rockford is most definitely defunct. Detroit and Chicago are more active than most probably think in my opinion, but are a shell of their former selves. I'd probably put New Jersey below both of them personally. I think you could make an argument that the Colombos are in pretty rough shape, but still are functional. In summation, I'd say 5 families and Philly are probably overall most active today, but its so much different than the days of old. It's hard not to say that every LCN group in the US isn't hanging by a thread.
