New to 4-H shooting

[fish and teach]

First let me introduce myself. I'm a chemistry and Physics teacher in Riesel, TX. I am going this week to get my shotgun instructors certification. My son and daughter are both just getting started in shooting sports. I have been looking for 4-H shoots to take them to that aren't too far from Waco. A lot of the shoots that I see listed have already happened. What would be the best place to look for upcoming shoots that are 4-H sponsored?

Thanks,
