As I exited Amtrak at Philadelphia’s 30th Street Station and made my way to the escalator destined upward to the grand train lobby, the oddest thing happened.

Like a scene from a bad You Tube clip, surprised passengers stumbled over their own feet trying to walk down the up staircase while spectators laughed out loud when suddenly, the irony of the situation struck me.
