I recently came across this article and thought that it would be worth a read. Now first I want to point out that there are many systemic changes going on both in the Red Cross and your local government to answer this question, but the question still stands.
Who will care for your elders in a disaster? What will they do if their power is out for a few days and it is too hot or too cold? How will they cook for themselves, or take care of themselves? What if their drop in caregiver can't make it to check up on them? What if they don't want to go to the shelter?
Give some thought to how you will care for them? From a distance? They need a plan too!
Get involved locally and find out how you can help locally.
