I'm with Pahoo
Regarding my grandkids, regarding everything I've done with them, I'm considered their guardian.
As for the range, I have my own, but I'm a member of Other clubs through out the state, No one has questioned that I'm their guardian.
Only problem I ever had was at lander at a rifle match, my grandson asked if he wanted me to pick up my brass, I let him, the cleaned the range of all the brass. That didnt go over real well.
