They could have been referring to the fact that some of them are on teams from CEA that are competing at Dallas.
YE is not going to dallas, they probably said UCA as they will be there. I believe only one team from K'ville is attending, one or two from Charlotte and a couple from Raleigh. Since most CEA athletes cross to one or two teams it would be problematic to attend NCA with the cross over rules in place.
Wow, I was hoping that YE was going to compete at NCA and not have to wait until UCA to read about these fantastic Y5 teams competing against each other. Although I do not have a child competing, I fondly remembered the excitement of the competitions... I hate to think that these 2 squads won't see each other, especially WC Twinkles being the only Large Y5, I will think they need the challenge that YE always bought...
