I was invited to a seminar in Green Bay last Spring, so I am a little surprised to see all their web links broken. I sent them an email, but haven’t reached them yet.
I would recommend you visit each dojo mentioned. Then you can determine if you can handle the trip regularly and if you fit in with the class.
The schools I mention are not affiliated with each other, but we all get along (we are all family up north). It is all what vintage you prefer to practice regularly.
