The most painful and upsetting thing about the two heart attacks I have had is the reaction of my wife.... she was and is so worried and it has changed her life. Anything I can do to assuage her current concerns, I do it, even if it gets in the way of what I would like to do while riding. Keep your family in mind, they have to live with what happens to you. A locater beacon or other such technology is cheap in the grand scheme of things. What do you think they will think if you don't think about them. Anything can happen anytime, that is the only thing I know at this point and I want my family to be protected no matter what happens to me.
