I wouldn't say that either of us are huge tennis fans (Tom certainly more than me since he had to explain the scoring to me on the way), but going to the US Open was something we both really wanted to do. We saw the quarter finals, one mens and one women's (singles games). I know we saw Sharapova and some American dude- but it was 2 years ago and we've forgotten!
We arrived very early so we had chance to explore the whole arena. They have several courts with many games playing at once, and lots of big screens to watch from outside.
We got really into our games, so much so that we actually didn't take any pictures during them! It must have been good!
The view from the top of the stadium was incredible. These shots of the Manhattan skyline in the distance that Tom took as the sun went down are still both of our all-time favorites.
