Detroit subway entrances?

I've read about these, and they sure look like stairs to a station, but I reserve judgment.  Still cool that there may actually be a subway in DETROIT, of all places.  (even if it is abandoned)

 2nd and Courtland Streets

2nd and Pilgrim Streets.

Chicken troll

Something you see on internet forums.  A creature with a loud initial roar of challenge, that almost immediately disappears.  If it returns again, it responds to any action with a nearly identical roar, followed by an equally identical disappearance.  It is basically harmless, but annoying, on the same level as a 'seagull manager'.
