Urban country

I'm working on a country song about public transportation, but I'm stalling out.

Here's what I have come up with so far:

Well the gold rush passed me by
but the gold line will be found

My horse is a light rail
and my pasture is downtown

Saddle up, boys
There's enough country to go around

My twang'll never leave  me
the next train comes at 10

Packed tighter'n sardines
good thing I left my spurs

Saddle up, boys
There's enough country to go around
