I have been thinking about putting together a supply kit in case something happens. But when you live in an area where you really don't have to worry too much about a major catastrophe, it's easy to put it off, but it's so much easier to just do it. I have 4 small kids and having no car, this past winter would have been a lot easier if I had some basics on hand. The items have come in handy many times since I've started gathering them, not just during disasters. Just be good about replacing anything you use.

Disaster Supply Kit
Water--1 gallon daily per person for 3-7 days
Food-- non-perishable packaged or canned food, juices, food for infants, snack foods
Utensils--non-electric can opener, cooking tools, paper plates, plastic utensils
Blankets, pillows *this came in handy when I had a sick kid who puked on I don't know how many blankets on a Sunday and I didn't have any money on my laundry card to wash until the rental office of my building opened the next day)
Clothing--seasonal, rain gear, sturdy shoes
First Aid Kit--prescription drugs, OTC medicine (pain reliever, antacids, etc.) *helps when you don't drive and someone gets sick in the middle of the night and you don't want to call and wake someone up to get what you need
Toiletries--Hygiene items (feminine supplies, deodorant, diapers), moist wipes
Flashlight, batteries, radio
Cash--small and large bills, and change *A life saver when I get called into work before the stores within walking distance aren't yet open and I need change for the bus
Keys *I can't tell you how many keys my daughter and I have lost
Tools--basics such as hammer, flat head and Phillips screwdrivers and wrench at the least
Pet care items
Toys, books, games--Age appropriate for everyone in family, including yourself
