I keep a list in a flap inside my suitcase of a couple emergency numbers. One to call if that suitcase is lost, another to call if I am injured (or worse).
I don't keep important papers in there in case it is lost, my identity info would be at risk.
In my car's glove compartment I keep another list of numbers. A tow service I trust, I know the owner and don't take that service through my insurance company. Numbers for my insurance agent, etc in case I'm in an accident and my cell phone is damaged, I'll have a backup list of numbers.
Babs, regarding the no picture on your license. It would be a good idea to request from your state's DMV a letter stating it is not a requirement, that you can carry with you when you travel to other states.
