Speaking of "The Rock", I had the pleasure of attending a Devils game recently at Newark's Prudential Center. It really is a very nice facility - and it's still new, so it has everything that comes with that. It's clean, and shiny, and not run-down. A great place to see a game.
The location is also convenient. It's just a few blocks from Newark's Penn Station. In fact, you can see it through the window at the station platform - that's it with the green-colored display screen on the side.
The only real inconvenience was the schedule on the Raritan Valley Line. Now that weekend train service has been drastically cut, it was necessary to board very early and arrive hours before the game. Conversely, we waited over an hour for the return train to Somerville.
With so few trains running on Saturdays and Sundays, wouldn't it make sense to coordinate rail service with the arena on game days?
