I am a beginner prepper from Oklahoma City. I have only recently thought of prepping after the events in Boston. I want to put together an emergency backpack that will last for at least a week in case i need to get out of town. I have been reading about essentials such as food, water, medical kit and so forth. I also want to prep my SUV at some point as well with more emergency supplies. Any advice for a newbie prepper would be welcome.
