I have a problem. I over pack. A lot. I cannot decide what is essential for a 72 hour bag. I think I have my entire bathroom in 2 bags, just in case. They are pretty heavy. I still need a bag for our water, food, clothes, and everything else. I don't want to be caught with my pants down, though. I seem to always be the one where if it really shouldn't happen, it will happen to me. I feel like I must pack EVERYTHING, just in case. What is in yours? Do you keep yours on you all the time, in the car whenever you leave?
