If you have any friends who are LEOs, I`d double check on the legality of having a firearm in that Camelback in the trunk. Since it`s not in the passenger compartment you might be okay. But back home in Ohio any weapon anywhere in a vehichle is considered a concealed weapon unless it`s on your person. They usually give a pass on unloaded firearms ,in locked containers, in the trunk. Since it`s out of sight inside the pack I can`t see you getting into any trouble unless you were arrested for something else and they found it while inventorying the contents of the car. But I`d still ask around. Better safe than sorry.
