My question has alot of moving parts so I'll try to keep it simple. I live on the Gulf Coast and travel across the state every week for work inside a FL Seaport that is Posted Weapons free zones and cross a checkpoint with security guard asking if I have weapons before being granted entry to drive my vehicle near the dock that I work. (I work on a tug boat). I'm a CCW permit holder and not legally allowed to enter the port with my firearm. This means I must transport to and from across the state defenseless at a time when I feel must vulnerable. Obviously a firearm is the best choice for protection but what is the next best option? Options I have considered are Flare Gun, Pepper Spray, High powered semi auto pellet gun. ( Note air guns are not considered weapons in FL). I believe I could get away with the flare gun since I literally work on a boat.
