Im going to this lake in Tennessee called Herb Parsons Lake(fishing lake). Everytime I go there i never catch anything off the bank really, i only caught small channels but there is big blues in there, ive seen pictures. Also seen some in an article in the newspaper. This Thursday im going there except this time im taking a boat out. They just started selling Skipjack so im wanting to see what that will do. I would like to know some key areas to look for that would hold big blues, but there is one problem, i dont have a fish finder or depth finder. Probably becomes tuff now right? Any suggestions?
