My beard is grey. The top of my head is ..."flesh" colored. I refuse to cover the grey, or get a rug or whatever. I am who/what I am.
JD, nice comment about your mom. I had a friend a few years ago whose response to getting grey was to dye her wild mane silver. You could spot on the street from about three blocks away.
FHN: nice pictures. Don't worry about the grey. Natural is much better than whatever comes out of a bottle.
