I have a dog tag but wish I had a bracelet. My husband and my father-in-law have been outfitted with wrist RoadIDs.

I know at least two people who were rolled into the ER as "Joe Doe" and "Jane Doe." That sucks. It means that these people's relatives and friends had to look for them by calling the police and all the local hospitals, giving the description of their loved one. In the case of "Jane Doe" it's a resident of the college where I used to live: after three days without seeing her, we had to get the police to open her room, and not seeing her there, calls had to be made. She was eventually found at a not-so-near hospital with a head injury she got skiing. For three days she was pretty much alone there and that must have been scary.

And remember that if you head is banged up, your cell phone probably will be too.
