+1 on the Ground and Pound chair, light quick and simple; I put some pads in the bag on the back for more elevation when needed. Add a gun, sticks of some sort, and calls thats all thats needed.
So I guess you could take the chair off the list if you wanted to sit on a prickly pear, stick tights, yucca leaves, snow, mud, etc. Could take the sticks off if your using a shotgun or want to freehand. I dont want to do any of that.
