I've worn the standard wrist ID for the past five years... this is Arkansas, after all, and internet access and cell phone service is spotty to non-existent once you get away from the larger towns. My faithful old yellow one finally wore out last winter, and I replaced it with an updated red band (& updated the emergency contacts as well), with a new yellow band in my things box in reserve ;-)

Haven't had to really use it just yet, but it's a comfort having it there. I also wear it when I'm simply travelling out of town as well, so it serves double duty ;-)
