The Road ID suggestion is a really good one. DH wears one. He says that he doesn't even notice it once it's on. I have an interactive medic alert bracelet that I never take off, so I'm covered there.

ID in a seat bag or pocket can be helpful, but I've heard that EMTs won't go through your stuff looking for ID. (Can anyone confirm or deny this?) Better to wear the ID where it can't be missed (wrists or neck) IMO. The insurance card and driver's license are good backup though, and I carry copies of both in my seatbag.

Kalidurga- good point about the pets! I need to make sure that our emergency contacts all have keys to our house. Thanks for reminding me!
