In another post, a contributor siad that he had been catching bass on VERTICAL STRUCTURE up river in Nolin. The poster didn't elaborate so I am confused about where to fish. (I asked him in the post and tried to emai him but haven't got an answer) I don't understand the term VERTICAL STRUCTURE and wanted to get opinions on just what it means to other people to fish VERTICAL STRUCTURE.

Thanks in advance for any help,

Grumpy
