I too use a portable blind at times and I try to nestel it into an area that will provide some natural cover. I also take some of the surrounding natural ground cover (Ie: ferns, dead branches, etc.) and dress up the exterior of the blind a bit to break up the outline and make it look more "in-place" with everything around it. It normally takes about 5-10 minutes of a little extra effort to make any portable blind look more natural in it's setting.
