I have been using the Hunter's Specialties Adjustable Backpack Blind. It' height is adjustable, having (5) telescoping legs (similar to a camera tripod) and measures 12' long by 27"-54" high (adjustable height). You can check it out at

http://www.google.com/products/catal...d=0CGgQ8wIwAQ#. This is a comfortable seat for attaching to a tree when surrounded by the blind. I also use the Guide Gear Swivel Seat

Getting back to the stand & your question. I have set up in the early afternoon and also early morning (well before light) with the stand and have had deer come by within hours. Wind is the most critical factor, so locate accordingly. I usually will brush in behind me. When dressed in camo & sitting behind the blind you would be tough to see.
Go portable - it works!
