I am not familiar with areas of Michigan, but Dr. Richard Mudd's youngest son, Tom, now resides in the family home in Saginaw, Michigan. He and his sister have both told me of the decay in that area also. Tom and his wife are very active in the historic preservation community in that town. The decay of our great cities of population seems to be systemic in the U.S. Taxes, greed, corruption, and social programs sure aren't helping.
