Dkdogdaddy -- an explanation of the nickname

What's a sixty-year-old doing with a nickname more appropriate for a cool, young, hip, homeboy-type?  It's a tag I received many years ago from my former young adult buds who have moved along with me into geriatric status.  There were "Gmurdog" and "Brad Daddy" to name a couple.  The bestowing of the nickname was an unofficial statement of acceptance into the crowd.  It stuck with me for decades.  One member of my family has mispronounced the "dk" at the front as "decay", which is not funny.  Nevertheless, I must reveal at the beginning of this blog that I am a mismatch for the cool, youthful moniker. I am a self-described old guy with gray hair, with the exception of one wild hair which will never turn gray!
