Bonus #1: The Softball Field at JFK Airport
Just south of Federal Circle near the Cargo Area A and JFK Airport Cell Phone Lot is a softball field that very few people have heard of. It is used by a small league formed of employees of the airlines and companies that service the airport, and not open to the public. Foursquare does has a check-in for the ballfield, with a single photograph. In the NYC Aviation forum, one user wrote that the ballfield is the same field Mickey Mantle hit his 1300th home run when the airport was Idlewild. We have not yet verified that claim.
