Some study said Holland, MI residents were among the happiest in the nation. Holland is very near Muskegon. Absolutely, stay away from Saginaw, Flint, Pontiac, and probably Bay City.
Michigan is a beautiful state, it has lakes everywhere. Wildlife is abundant. The people are friendly and welcoming (except for Saginaw, Flint, Pontiac, Detroit, of course.) Housing is now very cheap-everywhere. It is cheaper to own a home than it is to rent.
I have never been to N. Cali, I hear it is incredible. One thing I'd consider is what you would pay in taxes. Once Florida makes it legal I'll be there.
