My thoughts on using mirrors. I need to continually look behind me to be on top of any developing situation. I can't realistically do that by turning my head, twisting my neck or whatever. I cannot depend on my sub-par (putting it lightly) hearing. I live in rural central USA, probably more isolated than most of you, and I still feel that for safety sake I need that continual assessment. I recommended the take-a-look mirror earlier. The bar end mirrors I tried before that did not work for me. I know they work for some people. Everybody is different. One word of advise, the first couple times I used the take-a-look, I had trouble on the focus and was left with a bit of a post-ride headache. Luckily, I got past that. It is so much a part of me now, that when I am walking through the mall for example, I look to the mirror that is not there to check behind me!
