From what I understand all three of those places are about as bad as it gets in America, esp. Benton Harbor which I've heard described as just a smaller version of G.I. Just wondering if there's any rap coming out of there.
my boy tubbs is from youngstown and could hit you up with some youngstown stuff. he produces a bit of music for the local cats. ask him about it over at www.midwestinvasion.com
I got a couple local cds from here in dayton (I live about 15 min. outside of downtown) they're pretty good, Hip Hop Pirates - Bottle Of Rum (Mixtape) and J-Boze - Don't Sleep On Me both are pretty good
