When I travel, I carry a "manpurse" Maxpedition Jumbo Versipack that sits right behind the front passenger seat. In it, I carry a first aid kit, a pair of gloves, a large water bottle, a handgun, three magazines, as well as a fixed blade, a spare folder, a multitool, and multiple flashlights and batteries. In Florida, there are lots of sections of highway which, at night, are just miles long stretches of darkness. I make it a point to always be prepared. Have traveled with this gear for years, and have never needed it (knock on wood). But if I ever find myself broken down, I'll be ready.
