i used to live in a very small town, out in the desert
i lived at the end of an old, historic, mining road called Plomosa Road
i was at the base of a small mountain, so the road ended at my place :P
up the hill a little was an old abandoned mine

when you live in a small town, everyone makes up nicknames for you
we had "One-Door Fred" and "Bartender John", etc
one of the guys was an old guy we called "Dirty Ernie"
he used to grab at girls when he'd been drinking - lol
they called me "Dead-End Dave"

that's where dedndave came from
