Trike "On Star"

[dghasbar]

Does anyone know of a device like "On Star" that I could attach to my trike that would allow my family to find me if I had an accident. I did have one March 2004. A spiral fracture of my right femur and was lying in a ditch unable to get to my cell phone. Luckly some other riders passed by and helped me. I have looked into things for Altzheimers patients but they seem to be effective enough to track me anywhere. There are some that are attached to trucks, but they are not small enough to attach to my trike.
