I work out of my car, so I always have my GHB with me. I cover five counties so I have water, snacks, an MRE, an Esbit Stove and cook pots, some soups a couple of bottles of water, a poncho, liner, spare socks and a gore tex rainsuit. I also have a couple of different methods of firemaking as well as several dozen bottles of oxygen, regulators, conserving devices and cannulas. I think if my car went off a bridge and underwater I could still be alive a week later, LOL. I deliver Oxygen for a living.
