Ice
I have been thinking about getting a road id also so it is good to hear of preferences and what to put on it
Another idea I heard was to put ICE in your cell phone contact list.
ICE - In Case of Emergency and have it linked to whoever you want called, I was thinking you could do ICE2 etc if you want more listed.
I don't really know if emergency people would actually check but I thought it was a pretty good idea and I always have my cell phone with me
It's about the journey and being in the moment, not about the destination
