Hold up and wait a minute...your not the only one to think of that I happen to ride bikes and own a " third eye" mirror. My concern was that it might flash a deer also. I usually have my back to the sun, and you know how mirrors can flash from a long way away.. so I will keep mine on my Bell instead of my Boonie.

How about those sunglasses with the side view mirror? (thought of that sittin in a tree stand too.)
