Get that gear ready, gas up the truck, and hit the sack. Make sure your fishing partner, if you have one, does the same. The only thing worse than driving back home because you forgot your tackle bag is driving back to your buddy's place because he forgot his.
When you do get on the water, don't just slip into default mode and cast to promising spots. Pay attention to conditions and adjust accordingly. Subtle increase in wind speed? Maybe you should try a windward shoreline, where bait is getting trapped. High water? Look for areas that are newly flooded, which attract fish. Does a certain insect or baitfish species seem prevalent? Try imitating it, in size if not in color. All of this may sound routine and simplistic, but it's surprising how many fishermen will stick with one lure, tactic, or location simply because it produced once before, even if that happened during the first Reagan administration.
