We hope that the "Stranded at the Point" situation helped motivate you to look at the emergency supplies in your vehicles.
If you are just getting started, see the checklist posted in the Reference section. It's a good start, but keep the specific needs of your family in mind when packing.
If you don't have the time or resources to complete the checklist now, at least make sure you have some food, water, and blankets in a tub or backpack in your vehicle.
