There can be skunk spray smells in Sk1. Also from where I come from in E Ky, we never called it RKS, always just skunk, and not all of it was acrid skunk. I myself often find skunk spray SWEET myself.... My sister used to smoke, and is almost 70 years old. When she came to my house one time when I was growing Local Skunk, she told me my house smelled like a skunk. Thats from someone that doesnt smoke, doesnt care what RKS is/Means, and said the stuff I had growing smelled like a fresh skunk.
I myself never heard Skunk, called RKS until I started reading it on forums. First Skunk I evr saw was in the mid-late 70s, and was from Meigs County Ohio. The California of the East at the time. My buddy was told the skunk genes they gave him, had Kerala in it.
