RE: treestand or portable blind
PA made a good point(always does) I think that decision should be based on the lay of the land(I also hunt the coulees) People will push deer to you. It is to your advantage that your daughter and yourself(thats cool) spot deer before they get close enough to spot you. With twice the scentsightsounds a blind would be the ticket, but with a rifle, two sets of eyes, and attention to the above mentioned details I would get in a stand. Good luck to the both of you!
