Who Stole the Signpost?

I came out here to find Harry Partch
I drive the back roads
Mile markers ticking by
All the way from Barstow
To Big Rock Candy Mountain
Cigarettes grow on trees
Whiskey and soda bubble from rocks
I drove in vain
I look to see the shadow
Of Harry’s face
In the open doors
Of the one graffiti free box car
In a mile long freight train
Parked in the Mojave
I looked in vain
South of San Clemente
I search the coast road
For the remains of a one pump diner
Where the honking horn
Sounds like a Zymo-Xyl
Harry’s ghost is summoned to serve 5¢ gasoline
I sarched in vain
