We headed out to California
everybody tried to warn us
said we wouldn’t make it any further
than that worn out Chevy would
The whole song has something of an 'in your face', 'we were right after all' attitude, but I'm not so sure it's warranted. I mean, your friends tried to warn you of the dangers of driving long distances in a run down vehicle? Isn't that kind of what friends are for? Why throw it back in their face? "Ha, we didn't crash and die on a deserted stretch of highway in Utah when our spark plugs or something exploded. Screw you people who were concerned about us!"
Interestingly, Josh Gracin never actually says if they did in fact make it out to California after all. They did break down "a time or two", so maybe they just got as far as Kansas as said, screw it, auto maintenance is hard.
Suggested alternate lyrics, to reinforce the song's theme.
Headin' out to the West Coast
Everybody tried to give us advice
Said make sure there's air in your tires
But we sure showed 'em
Drove all the way on just the rims
We weren't crazy!
