Many duck hunters, myself included, are on the web trying to gleen any information possible to help in the upcoming duck hunts. The web can be a great tool to learn about new places to hunt and possibilities that look promising. Don't worry, I'm not advocating trolling internet message boards for specific places to hunt, in my experience that has not led to fruitful hunts.
So what am I suggesting? Google maps. Here is a quick synopsis of how I use google maps to hone in on possible hunting spots. First, type in a city of a place that you already hunt (this really helps to understand how to use the tool). Make sure you click on "satellite" in the top right corner of the map. This gives us a bird's eye view of the terrain. By using your mouse move around and find your hunting spot. Notice the terrain around it and put it in your minds eye the reasons that ducks like this spot. Almost assuredly there is water there (unless you are hunting on land). Do you notice in the picture emergent vegetation? Agricultural land around the water?
From here we are now going to search out new spots. Start dragging the map in a direction you wish to explore. Look for similar terrain as that of your favorite duck spot. Notice points, islands and other features that would make high quality hiding spots. Are their funnels where the ducks will likely bunch up on their way somewhere? You get my point.
Now, cyber scouting will not remove ALL the foot work you need to do, but I guarantee it will make the time you do spend in the actual spots much more efficient.
