I stalk and still hunt with my bow and do not use a ground blind at all. I find hunting from the ground a great challenge that can not be compared to. The feeling of having a deer walk by from 10-15 yards no one canimagineit when just sitting on the ground at their level... I would find a spot that they are traveling in and out ofby the ditch you mentioned. I would use redfox or raccoon cover scent as well. (The cover scent should be of something that would normally be in this area..) If no luck find an area that they are travel in and out of to get into those bushes. Sit near by that area where you will get a good shot. When sitting on the ground use very little movement as it most important in this case. Good Luck..
