I think it could be better worded to, what worked yesterday might not work today. As for spots, If i can consistently get on fish at a spot than i dont see why i should stay away from that spot. You cant fish perfectly, and even if you did wait till you are on the water to make a plan that doesnt mean you are going to tie on what they want. You cant predict fish, and even if something worked yesterday that doesnt mean it wont or will work today.
