I am an overseas Mudcatter, but then we all are to someone else! I did know what a copperhead was, thanks. I think the choice of that name for the road gives it a nice threatening edge which fits in with the fact that people keep disappearing down there.

Bobert's line makes sense and I'm quite happy with that if no-ones got any better explanations. I hate singing lines I don't understand. I'd never considered singing this particular song but I found the riff works brilliantly on the Irish bouzouki my wife just bought me and it was too much funto pass up.
