I've taught Hunter Education in schools from the 1980's I always got a letter from the school principal and informed the local police about the details; date of class, time of day, etc.Carry is allowed in both places "with written permission." Curiously the law does not say who can give such permission in either location.
That raises the question of who can grant written permission... For example can the clerk of court give permission? The law is silent on the issue. Can a school teacher grant permission to carry? The principal? The janitor?
After the shooting in Colorado in 1999 a school asked me to teach a class and I contacted the local Police Chief about teaching Hunter Ed at the school and he asked me do the class at the police station. It worked out great.
