Really, it’s a cliff that’s covered with catnip. Bring your kitties close for a good sniff.
Catnip is a native wildflower in most of the United States—try stopping any mint from growing wherever it pleases—and for some reason it outgrows everything else on this rocky hillside. I guess the local cats are accustomed to it, or they just take on what’s growing at the top.
In order to understand the title, you have to know an old traditional song called “The Big Rock Candy Mountain”. If you don’t, don’t worry!
