The way I think of it, most of fishing success involves knowing where the fish are. I'm not going to have as much success fishing a new lake as I am at my old stomping grounds. I wonder if LMB aren't the same way. They might learn the new pattern eventually but they'll lose weight in the meantime. The main difference between me and a LMB being that when I strike out at the lake, I can still go to the grocery store.
