Odds and Ends:
All the medication you will need for an extended time in the govt shelter or in the boondocks. Condoms are good for carrying water from the national guard water trailer. In your car, a box of condoms and lubricant, a couple of cheap pocket knives, ammunition and some NSAIDS to trade for other goods or services.
You must be able to text message with the cell phone as voice communication is the first thing to go out. The text messages que up at the repeater and usually go through soon. Many people had their cell phone batteries (bring a spare) run down while they made many attempts to get a signal.
In earthquake country the home phone (land line) system will go down because most of the receivers will be off the hook for days on end. Remember there will be no police, ambulance or emergency service for at least three days after an earthquake.
