A South Carolina Musical

The other day, I was thinking about how the state of Oklahoma has its own famous musical named after it. But my new state does not.
I was working out in the garden at the time, walking around on the magnificent layer of pine straw that covers all of my garden beds. I asked myself “What do I know of the musical Oklahoma?”
The two lines I could recall were, “The corn is as high / As an elephant’s eye.”
Suddenly, words came to me: “The pine straw is as thick / As an elephant’s…”
But I just could not come up with a rhyme at the end there. Anyone has any ideas, send them my way.
