Today was amazing. I showed up to the Water Cube just in time to catch Michael Phelps swimming freestyle for his 3rd gold medal. Man, is that guy fast! Trying to photograph him swimming freestyle is almost impossible. He rarely came up for air and when he did, he was so low to the water line that you could barely capture his face.
Luckily, he ended up swimming a qualification heat for the butterfly stroke not long after his freestyle win, which is a much better stroke to photograph.
