Wolfy, If you like this game you should look into buying a dog, it will change your life. I used to beat the brush too. I went out with a friend and hunted over his brittany. I was changed for ever. I own 2 GSP's and am going to look at a new girl on Friday. If she lives up to the billing she is mine. I can't live without the bond I have with my dogs. Ladybird will tell you the same thing I am sure. But now to your real question, all the hunting mags have part of the information you want. These are opinions from good hunters and offer some good tips. But a biology book on upland birds teaches you real needs of the bird. These needs change through out the season, if you understand the needs you will learn where to look for birds in certain situations. It was the best thing I did for myself. I can go to Kansas or ND and find birds. The cover is different and there fore the birds are in different places but the needs are same, so you have an idea of where to start.
