Jaunted blog recently ran an interesting piece on New York’s Citi Field stadium, where the Mets play their baseball games. Whilst those in the highest seats have usually paid the least for them, and suffer the long climb and distant views of the game, there is actually the benefit of having a view of arrivals at La Guardia Airport. Planes will also depart right over the stadium.

Take a look at the blog post here for an interesting picture of what you can see.
