On Twitter I saw this "Amber Alert" this morning. My first question was where did this occur. The location seemed to be South Carolina. That shouldn't matter too much because we live in a country that someone could fly across in hours. Mexico or the Caribbean are only hours away. A missing child could be taken anywhere quickly. It's good that everyone can know via Twitter.
On a related subject also on Twitter David Stephenson posted a link to his emergency tips
I hope that those evacuated by today's terrible Southern California fires or having any other emergency can find and use some 21st-century communication resources.
