Well, it is no secret that the vast majority of "Seed advisory council" members were parents that had sent their kids to the lauderdale seed. They were a group of influential parents that formed a committee to bring the Seed to St Pete. There in that cozy little group is where we find Charlie's dad.
So was he a seedling? My bet is yes. Do I know this for sure? No. I don't personally remember him.
Does anybody?
