Using this site as a guide I just finished my own BOB. I purchased many of the same items with some slight variations based on my local geography. Since I was starting from scratch I didn’t have many of these items yet so most were recently purchased. Right off, the tent, sleeping bag, ham radio and titanium stuff are about 800$ after getting all of the other items I am right about 1500$. However, some of the items I got there were cheaper options but I chose better quality to ensure the equipment lasted a very long time.
One thing that the article doesn’t reference is “How many people will there be in your Bug Out party?” The point being, that although there are some items that need to be in everyones B.O.B, there are others that don’t require duplication. Figuring out which items can be used by all the members of your party can reduce duplicating these items in each bag. For example, does everyone in your party need to carry a 1 quart backpacking pot, or will 1 or 2 suffice for your whole group? Those types of items can then be parceled out to the members of the group, and cut the weight down.
Ideally, when traveling in the wilderness, it is best to carry multiple fire-starting tools, such as a lighter, matches, flint and steel, etc… Even with these implements starting a fire can be challenging in inclement weather. We highly recommend practicing fire starting in different weather conditions within different habitats. Good fire-making skills are invaluable. If you were to find yourself in a situation without a modern fire-making implement, fire by friction is the most effective primitive technique. Popular friction fire-making methods include bow drill, hand drill, fire plow, and fire saw.
