MudderChuck was my board name on some other sites. It was MotherChuck when I was starter at the local Mud Races, got Changed to MudderChuck somewhere along the line. Mother was a generic nickname, for the guys, that did safety and tech, inspections for most types of racing, back in the old days.
I started using 8Mud here, because my my old name offended some people, with lively imaginations.
8Mud is what you do, if you smile, while starting a mud drag. Also the answer you give the wife, when she asks how the race was.
