RE: Ground Blinds...
I would also recommend gettin in a tree stand but if you want to hunt from the ground i would definately suggest a natural ground blind such as a cedar or pine tree. If you just got pop up a double bull the deer will notice something different in their environment and will get spooky most of the time. If you are going to use some sort of pop up blind and cant leave it out then you will just have to brush it in like crazy to break up the outline.
