I normally carry just my cell (wife's number is 1st in PhoneBook), my license, my insurance card, and $20. Now that it's frigid, and I'm wearing long sleeves, the chances that an EMT will look for a RoadID wristband are as good as them going through my pockets and finding my ID.
Eh...I'm not a jewelry or 'things hanging off me' guy. No necklaces, wristbands, anklets or anything like that. Maybe I'll get a tag for my nipple ring.
/made you look.
