[Aimee Wilbury]

I'm thinking.... they were all equals. And friends. Playing for the heck of it. And that there was no pressure to be better than each other.

I think the no pressure aspect was a large part of it... although there must have been times where they thought gee, this is a great opportunity, we better not screw it up.
