Don't you dare think you can just buy one off the street. In 1998, my brother took me to the game, and we bought tickets from a guy on the street.
Got in ok, but as we were going to our seats, a usher checked our tickets as we were heading to our seats. She held us with her until the police arrived.
They took us down to the basement, in a room, and interrogated us. Turned out the tickets were fake and we were almost arrested because buying tickets from random people on the street is illegal there.
As we were being escorted out, I remember feeling grateful that we weren't going to jail, sad that we spent so much money. The police felt sorry for us and sold us two tickets at costs in some great seats and we got to see the game live anyway.
Grateful for those guys. Saw history.
