Hmm, decided to look before I go to bed.
"The phrase “school safety zone” pertains only to publicly funded primary schools. Public universities are considered public property, where it is not actually illegal to carry firearms, Fulkerson said."
Reading the ORC, it sounds like being ON the school premises or in the school is the safety zone. Still looking for clairification.
I may be getting the zone goofed up with the zone they have setup for drug distributors. But I could swear I've read in plenty of places it's 1,000 feet because of people who live next to a school.
