You have to realize the fishing is either "on" or "off" for the night.

If it's dismal, there ain't no sense in sticking around for more punishment unless you have another location you can quickly get to where conditions are different. All this talk of "when" the fall run will be starting....it already started people, but we are still plagued with inconsistency, even the bait guys are not hooking up every single day.

So have a plan, and stick to it. If things are off for the night, learn to recognize it and cut your losses so you can come out again.
