My son tried out for football at our community center
How old is he? Is he excited? 
he's 4. He just wants to run around and play. I'm the one that's excited. And I know nothing about football.
You will grow to love it. Football is amazing sport. Your son will love it. 
I hope so. I just wish it would get cooler outside before they start practice.
Just wait a few years. If he sticks with it he will be at practice 6 months a year then playing games in the snow.
We don't get much snow here maybe one good day.
