You guys may or may not remember, but Redbeard broke his collarbone last year when someone opened a car door into him while he was on his bike. We were really lucky he was conscious when it happened and called me or I would have had no way of knowing what happened for hours, and honestly I would have been a complete mess. I've carried an ICE card in my wallet for years, but this is even more convenient and it could really make a difference in an emergency.
