To prepare, you simply need to set aside a sensible set of supplies. You'll need food and water. Oh, and a big ol' bat! But, seriously, you can build up a supply kit by investing as little as $10 per week on the things you'll need for any emergency.
One week, buy a small first aid kit. The next week buy bandages or gauze pads. The next week, get some nylon gloves. The next week get a flashlight. You can assemble a nice kit from things on the drugstore shelves just a little at a time. When you go to the grocery, get an extra case of bottled water or get a couple of cans of chili, beans, or vegetables.
