I travel for a living, and the answer to your question would be based on how and where you travel. If by car, it is pretty easy to have what you need with you in a tote in the trunk. Be sure to equip for the expected extremes of the climate you are driving into. Always have a way to carry the most critical gear if you have to walk. Even if you car pool, don't be afraid to toss in a small extra backpack with your survival gear in it.

If you go by air, it is a little more challenging, but still do-able. In my checked luggage, I always have walking shoes, some heavier casual clothing, a hat, a large swiss army knife, mini BIC, whistle, AA cell LED flashlight, small FAK, water purification tabs, button compass, and local maps.

You won't be walking back to Utah from Louisville, so bring what you think you will need if you have to walk to a public shelter for a few days. Consider if pepper spray is right for you.

I also carry a few basics in my computer bag, as the SHTF event might happen while I am sitting in a meeting room somewhere... a small LED flashlight, a small swiss army knife (classic), a bandanna, a mini BIC, a whistle, a button compass, phone charger. Also, I have a little cash stashed.

Lastly, I always dress as comfortably as the situation allows. I can usually get by with Dockers and long sleeve Eddie Bauer shirts. I always consider if this is the set of clothes that I would want to wear for three or four days in a sudden emergency where my checked bag is back at the hotel, and I am sitting in the gym at the local YMCA. If you are a person who wears spike heels and micro-minis to work, you need to have your emergency backpack with you at the place of business.

There is no one perfect list, as it depends on your personal needs, your mode of transportation, and your environment along the way and at your destination.
