I strongly encourage getting one, too! I downhill skate in the country hills and mountains out of state sometimes. Injuries can happen, so I got one for that.

I've had it for a year or so. I've got the wristband with the immediate, need-to-know basics: my name, two contact numbers, my blood type, and allergies (none). I've made a habit, like someone posted before, of strapping it to my helmet when I'm not riding so I never forget to put it on. There's always the morbid thought of losing an arm, like spindizzy said, but hopefully it won't be too far away from me.
