I was driving down the interstate many years ago and my son leaned over to me and asked me what my handle was. I told him I really did not have one and did he have any ideas. His come back was how bout bigdog. Then the wife piped up and said YEAH dog spelled as dawg. The last two letters are my initials of my name and were added at the end because when I joined the dieselstop.com forum the name bigdawg was already taken. So I added the letters at the end.
