Here's one: relinquishing those items and boarding a plane to fly across the country.

For many preppers, a worst-case scenario for us would be if the SHTF while we were traveling.  If your journey is by car, you can be fairly well-prepared. However, if you are flying, the TSA has basically neutered our ability to care for ourselves in the event of a disaster situation, you know, "for the safety and security of the traveling public," to use their own words. Didn't these rulemakers see the movie Cast Away or the series Lost? If your plane crashed and you were stranded on a deserted island, how on earth are you supposed to open a coconut with what you're allowed to bring along?

Remember, what you pack in your checked luggage may not be available in the event of a disaster. You can only count on what you have on your person, and that makes the contents of your carry-on bag particularly vital.

Since there's little possibility of being able to sneak items onto a plane, you have to do the next best thing: you must work within the rules to create a bag that could see you through a variety of unexpected situations.  Despite my strong personal feelings about the unconstitutional air travel checkpoints, if I want to get on that plane, I can't carry my normal EDC kit, which reads a lot like the TSA's current list of banned items.
