I walked right by this statue on my way into the game. I didn't notice the trash accumulation but I went in about an hour before the game and I don't know when the picture was taken.
That being said, I had a drink with me when I walked in and needed to find a trash can, there was not one anyone near the line. I knew that if I carried it in, they would ask me to throw it away, at that point I found a trash can just inside the gate which I had to reach through to get it in the trash can.
I'm not defending the folks that did this, but the Rangers have got to be more realistic in providing a place to throw away things that can't be taken into the game. Otherwise, they are going to end up with a bunch of junk either on the statue or littering the ground outside the stadium.
