HI susi_q,
Have you ever heard of the Vial of Life program? We have worked with it through our first responder/fire units here in town. You would have to call around to see if anyone is using it, they would probably love to have more help with it. Call senior resource people, fire/rescue. Here is a good site to give you info on it, plus some downloadable, printable decals.

They use a baggie on the site, we use a medicine bottle. One of the drug stores donated some for our use. I'd be happy to help you with any info I can give you...just ask.
