i would say thats about right... i wouldnt be too afraid to wait even another week or so if your cofident you will get some rain. Dont worrry about if the field is lush and green all over, the deer will start using it as soon as the first bit of grass starts coming up.. the field not bein full at first can actually play to your advantage as a bow hunter, the deer will concentrate on the part of the field with the most grass when its not completely filled with grass and you can rele tell where they are gunna be in there and set up for a chip shot.
