This message is off topic to address the non rail points raised by Mr. Buddah (as such, if it is killed, I'll understand).
Quite obviously, the Chicago Symphony is being quite "mum" about the whole "Brawl in the Hall" incident (not aware of any "To our patrons, we are deeply sorry about...." letters out there). I can't think of anything that has caused them embarrassment to this extent. Since i wasn't there, I can't positively be certain what caused such, but I'm willing to bet that it came about owing to the protocol that is delineated both at the CSO's website as well as in the programs that in the Box seats (about $200 a ticket) patrons seated in the first row of three during the first half of a performance are expected to relinquish those seats to the patrons seated in the third row. It seems fair and square to me (I've never done Boxes at Orchestra Hall, but have at Carnegie Hall in New York), but in this yeah for me and fuck you of today, it is no wonder and incident such as this has occurred.
Now regarding Downtown Detroit, I am reminded of the movie
"On The Beach" and scenes at "the end" showing an abandoned city. It is clean and the abandoned buildings have been "boarded up' with murals. During daylight hours, I think it quite safe to walk about, however for the Symphony last year, I took a taxicab to and from the hotel and surely will do same this year.
But to end Amtrak related, I am astounded how the line could have deteriorated so badly over the course of one week; unless the "baddy bad' is East of Ann Arbor.
