What does your name stand for InkJunkie?
Actually can be one of two different explanations...
oc = I live in Orange County
dart = my current '69 Dart currently in 'build mode'
...or...
the very first car club I belonged to back in the very early '70s when I owned a '69 340 Swinger was the Orange Coast Darts.
Take your pick...either one will work.
