At some point after Bowman went to prison I've read they moved National from Detroit to Milwaukee and Milwaukee Jack Rosga became National President. He ended up with a very long prison sentence, I think under RICO.

Should be plenty if you google it.

Looks like that HA Nomads was started a couple years ago. I think out of the upper midwest states now the only ones that don't have crossover chapters is HA in Minnesota and Outlaws in Wisconsin (maybe indiana too?)

Not sure who's in Iowa besides Sons of Silence.
