I have just purchased a large internal frame back pack from Bass Pro that i am using for my BOB. I have been reading a book called "Build the perfect bug out bag". It has a lot of invaluable information. I am wanting to know what some of you are putting into your BOB that you think is critical. So far for my BOB, I have purchased some first aid supplies that i will pack as soon as a find a small enough container or some water proof bags to cut down on weight. It is only myself that will be bugging out for now. I have thought of some freeze dried food, dried fruits and nuts for my food supply. I am not totally sure on the amount of water. I am thinking 4 or five liters will be a good for the first few days with a small water purifier. I am trying to stay within a budget on my BOB. I have saved more on the side for one handgun or rifle later on. Any suggestions about clothing or cooking gear will be welcome.
