Please tell me about San Diego

Well, there’s a fly in my soup, gum on my shoe
And I’m stuck in San Ysidro with a case of the blues
Oh, it can’t be so hard
To get back to El Cajon Boulevard

Now Ocean Beach is breezy, you can live like a bum
Mission Hills is cool, but it sure ain’t much fun
Julian has clean air, but it’s too far to go
Now I just want to get back to the only place I know

But there’s a fly in my soup… etc.
