Check out the maps on bing.com and use the birdseye view. If the satalite photos were taken in the winter, you will have a very clear view of your hunting spot. You can zoom in very close and ever rotate directions on the map. And best of all, it's free!
I agree with hunting the funnels.... I try and get away from field edges and into the timber always where the funnels are. But that because I have never killed a booner out of a field.... He'll go out there but you will need a spot light to kill him. If a Big buck will let his guard down in daylight hours, it will be in cover... or at least that's been my experience.
