I love it!
Patna, if you haven't seen Detroit lately, then you should take a look. Downtown has made a great comeback from when it bottomed out in the '80's, and they're holding the grand opening this week for the new river front promenade that extends from the Belle Isle Bridge down to Joe Louis Arena. The river front transformation is absolutely amazing! As far as the grade or value of your banknote, I have no idea. I still like it!
In answer to Toast, Detroit is the county seat of Wayne County, named after the same General Wayne that Ft. Wayne Indiana was named after.
