Sorry, it was a loooooong week. On a happier note, somebody alerted me to a notable attestation of Wisco, adj. 'from/of/in Wisconsin': The Volebeats' 1997 album, Sky and the Ocean, has a nice tune on it "Two seconds", which opens with this:
Just a guy from a Wisco town …They were from Detroit, but I don't know what Sconnie connections they had. The /t/ in town is virtually unaspirated, something you can get from certain speakers from here, but the pronunciation is pretty much shot through with things that presumably aren't regional, like reminisce with an /o/ like middle vowel. But it's a really nice song, as you can hear for yourself here.
