Visiting Detroit Sunday September 24th

I have a bit of a silly question.  Colleen and I have a 6 hour layover in Detroit and wondered if we know anyone close enough to visit for a few hours?  We are due to arrive Sunday midday at 12:10 PM and leave at 7:06 PM from Detroit-Wayne County Int'l.

 

Maybe someone has a recommendation for the 6 hours?  We will have just finished 14 ½ hours travel from Taipei so napping might be most suitable, but not as much fun!
