I'm not sure about AZ, but to be on the safe side
be sure you're not involved with any illegal activity
No loitering or drinking or those type of things.
....OK....I'll use google for a sec....
well, I looked here
you need to pay close attention to chapter 31, look under minors and also storage
if you happen to know any law students or if any parents that are lawyers
show them the link and chapter 31 and ask for help.
Be sure to study the ARS under weapons and know the stuff chapter and verse yourself.
