Have Kids Wanting to Swim in an NFL Stadium?

Just got an email from the Jax Kids Triathlon organizers regarding the Kids Triathalon scheduled for May 2 & 3.  I have one kid doing it. There’s room for more. They want more! And, they REALLY need volunteers. We’ve never done one of these, but I hear it’s a blast. And, this year’s swim is in a pool built inside the Jags stadium. What?! Anyone have kids who have done this?
