From Here

I've gotten good at missin' her

I practice all the time

While I drive the Pan Am highway thru

With that cactus friend of mine

It's gettin' hard to see the white line rollin' by

I can't forget her memory deep inside

I dropped a bundle down in Panama

But the loss didn't do me no good 

Spendin' cash and talkin' trash

Don't do it like it should

I realized I just couldn't buy her smile

I'll keep tryin' on that Pan Am mile by mile

If she'd meet me in San Salvador

I'd buy her a drink or two

We'd talk about our used to be

And ride on to Peru

The time to get it right is here and now

If she won't I'll move on anyhow
