A great tip from David Stephenson: Keep ICE in Your Cell Phone! Basically the idea is simple, put "in case of emergency" contacts into your phone's contact list as ICE-1, ICE-2, etc. That way, emergency responders can look in your cell phone to find out who to contact. Of course, they have to know to do this, so we need to get a critical mass of people doing it and get a little traction. I'm in.
