Personally if I see a pack of boats fishing in a area that I was originally going to. I will go to another area and fish. I will go and find some other school of fish to fish for when I am trolling. I found out if fishing bye myself not a boat near me the fish are not to finicky. If to many boats in the area seems like the fish shut down. The water is not like it was in the 1980's where you can fish on top of each other. What I am trying to say is that I avoid those packs of boat either I am drifting or trolling.
