Philadelphia has the 9th and the 23rd tallest buildings in the United States-Golden Gate Bridge anniversary 10 days before the 10th anniversary of Comcast Center opening.

Interesting that 10 days before the 10th anniversary of the Comcast Center in Philadelphia opening is May 27th. 
So the 81st anniversary of the Golden Gate Bridge is 10 days before the 10th anniversary of the Comcast Center being opened.
The Comcast Center is the building I mentioned in regards to Happy Gilmore learning to putt on the Earthquake Mini Golf Course. 



Also a block away from the Comcast Center in Philadelphia is the Comcast Technology Center that is supposed to be finished in 2018. No coincidence these Comcast buildings are the 9th and 23rd tallest buildings in the United States. 
Of course it would be on Arch Street as well, where Betsy Ross supposedly sewn the first flag at 239 Arch St.
