Just because the citizens in Arizona can carry does not mean we all do. It's up to the criminal to figure out who is carrying.
Did you give any thought to the fact most in Yuma parks are not residents of AZ or even The US and do not have the right to carry in AZ? No guess not.
So stay in Ca. where the only armed folks are LEO and criminals. Then consider this. If the criminal wants your stuff and you need help in seconds the police are only minutes away.
