Their are some differences and similarities between Citi Field and Yankee Stadium. Citi Field has an apple that pops up whenever the home team hits a home run and has a parking lot outside. At Yankee Stadium, their is a busy road with a subway station. I am also amazed about how much of Yankee Stadium is covered in pigeon spikes. On the pipes, on the frieze, on the lights, on walls, their everywhere!
