It's been my main username since first trying to come up with a "handle" in the earlier days of the internet
(1997-98ish). At the time, I really liked this song by a band called "Alice In Chains" entitled "Don't Follow". The first lyrics are:
Hey, I ain't never coming home
Hey, I'll just wander my own road
Just really liked the flow of it and shortened to nevercominhome. Sheeesh! How has 15 years passed so quickly?
