Q: Where can I open carry?
A: It's probably better to list where you can't carry. Depending on whether you have your license or not, some areas in state parks may be prohibited -- see their Firearms Regulations Page for specific information. Detention areas such as court houses, police stations, and prisons are off-limits. New Castle County has an illegal ordinance prohibiting possession of firearms in county parks. Title 11, Chapter 5, ยง 1457 allows you to conceal your weapon onto school grounds with a license or open carry without. However, there is the federal Gun Free School Zone Act which only exempts you if you're licensed by the state in which the zone resides. It's been suggested that Delaware's slot casinos are off-limits as are all federal buildings; however, we cannot verify this in law. You may not carry at Post Offices, including their parking lots. Some municipalities prohibit open carry on their property or during the course of municipal government meetings. Additionally, you may not carry a loaded firearm if you are legally intoxicated (>= +.08 BAC).
