BTW, for an extra $5 they will etch additional info on the back of the RoadID tag. You have to e-mail them about doing this. The last line on the front of the tag on mine (and my wife's) says "MORE INFO ON BACK!", so I essentially have 11 lines of info. Also I think it is better to have full date of birth (rather than just the year) as that is the key to medical records, especially with duplicate names.

I also use the FREE RoadID app so my wife is notified if I stop for more than 5 minutes, e.g. lying in a ditch somewhere (you can manually suspend this feature if you stop somewhere for a break). She can check my location anytime too.
