I went to college in Boston so I have been to the only other classic old school ballpark, Fenway Park. I actually lived down the street from Fenway Park. Walking up to Wrigley Field, seeing the open bars on the street, even the smell of the place, really sent me back a few years. Certainly at Fenway Park they never mentioned that I was there. LOL.
On the side streets there are apartment buildings. The owners of these buildings had built bleachers on the top charging fans for a seat. Most of them have a one cost including an all you can eat hot dogs and hamburgers included in the fare. This building has even created a restaurant below.
A few years back the owners of the Cubs decided they were providing the entertainment so either the owners payed them a percentage of their take of they would block their views. An agreement was made and I was told that the affiliate fee to the Cubs is 17.5%. Not bad.
