FYI, 100% of Acacia Park is within 1,000' of Palmer High School.
The Gun Free School Zones Act states: (A) It shall be unlawful for any individual knowingly to possess a firearm that has moved in or that otherwise affects interstate or foreign commerce at a place that the individual knows, or has reasonable cause to believe, is a school zone.
Title 18 U.S.C. §921(25) The term “school zone” means— (A) in, or on the grounds of, a public, parochial or private school; or (B) within a distance of 1,000 feet from the grounds of a public, parochial or private school. (26) The term “school” means a school which provides elementary or secondary education, as determined under State law.
The GFSZA provides for some exceptions, one of which is within 1,000', but not on school property, provided you have a concealed weapons permit AND state law says it's ok to CCW within 1,000' of a school.
Don't let this scare you off from OCing here in Colorado, as many of us have made this mistake! I pays to Google Earth or Google Map your intended walkabouts to make sure you're steering clear of these dastardly un-American zones.
