When ever I am out and not carrying my wallet, like on a run or bike ride or other activity, I use a Road ID

I have two of them. Both red bands for my ankle. I have my name, city/State, wifes name and cell number, my conditions that are medically important, and blood type.

I am not affiliated with RoadID but every one of my training partners also uses one when training and it absolutely has come in handy. Since we are usually wearing shorts or bike tights its extremely noticeable on the ankle. I realize when wearing pants its not feasible so in 2009 I am looking at the yellow wrist band.
