I've chatted with Sierra a bit, and I think Shane just took an interest in coaching her. I'd be surprised if there were anything fishy going on. She's at all the big events, and I've seen her in the VIP seats for the US open a few times. I think she got to get right on the floor and hang out during the victory ceremony because basically, a cute teenage girl can get away with that sort of thing. If some of the dozing 60 year old dudes tried that, I think someone would start yelling for security. The US Open is pretty informal though. If I attend another I'm just gonna try to bluff my way down there. Maybe wear some tight jeans.
