I used to routinely take the NE Corridor line when I was working with the Trenton Titans, and walked over through Mill Hill. I was strongly warned against doing this, but weighed it against route 1 traffic between New Brunswick and Trenton, and chose to take my chances. I was younger then, and could run faster, too.
Last night was total incompetence by the city of Trenton and the Trenton PD. Luckily, I parked in some NJ Transit facility just behind the light rail tracks, as did many here, and walked the block and a half over, hoping my car would still be there (it was). People were still streaming in at halftime, it was a huge disaster, unless you got there before 6.
Not sure all the complaining about the arena, I thought it has been well kept-up, particularly since there is no "main tenant" any more, since the Trenton hockey franchise folded several years ago.
