(2) As used in this section, "school property" means the grounds or facility of any kindergarten, elementary school, middle school, junior high school, secondary school, career center, or postsecondary school, whether public or nonpublic.
*****************
A ZONE is in a seperate statute, so it seems is NOT applicable here (there is NO provision for "firearm vs school ZONE"), so the post/quotes dealing with that issue ("...that damn gun") seems off-base.
