Thanks! I completely forgot to update this thread over the weekend.
As mentioned, Cedar Park advances to the regional semis. Celina also advanced in 4A DI Region II where they will play Stephenville in what should be a fantastic Thanksgiving weekend battle.
We did, however, lose 3A champ Whitesboro who fell 60-19 to Bushland.
Bonus fun fact: if Celina and Frisco Panther Creek win this weekend, we'll have a battle between 1st and 2nd place in 4A state marching band for the Region II title. In fact, the top 3 in 4A are 3 of the 4 remaining teams in Region II.
