As a follow-up to my earlier post there's a lot to fix, I found some photos of Shea that showed the railings. I liked the ones that were at Shea because they blended in with the seats and were not obtrusive. MetsPolice.com has been following this post as well.
We see Shea's Upper Deck and Mezzanine walkways up close and we can see how the railings and steps were just not in the way.
