LOL. You make me feel like some sort of magician or something. :)
Basically I know because I was there both weekends in Vegas. Last year, one of my friends was mistaken for Ryan's wife by a non-Whoser. When Ryan pointed out the woman who really is his wife standing behind him, we found out he had family in town. This year, Ryan was alone (family-wise) and spent much more time with the fans.
