So that begs the question- who/which was the most memorable moment/athelete at these Olympics, out of Phelps and Bolt?
I have to go with Bolt.
A friend who I was talking to about the race complained about Usain being arrogant and cocky. I think hes allowed isn't he? He is the fastest man alive, and dead, in both the 100 and 200 metres. He also helped his team win the gold, and break another record in the 4x100 metre relay.
Ye olde wiki makes for some good reading - http://en.wikipedia.org/wiki/Usain_Bolt
