Harrison Township, Michigan goes to Harrison City, PA. I then tried the city to the south - Saint Clair Shores, MI and that took me to San Antonio, Texas. I'm working in East China, Michigan and that took me to East Chicago, Indiana. I ended up just using Detroit, MI to get anything useful. So, no, that doesn't work either.
