I finally got myself a Road ID...
What a freaking brilliant product. For just $20 a runner/hiker/cyclist, etc gets the peace of mind knowing that if anything happens to you while on a run, your medical information can be readily accessed by an EMT. With just a simple phone call, paramedics can know what medications your on and who your emergency contacts are. As a severely asthmatic runner, I think it's freaking stupid I ever ran without one.
I opted for the sport band style, but you can bet your booty I'll be trying the other styles, and buying one for my runner/hiker dad, running kids, and running friends.
