Natural ground blinds are easy money on whitetails, especially when you can't get up a tree. Not so sure about commercial blinds, but I've even had hunters walk right by me without noticing my natural blinds. You could set some posts or use trees to tie up camo burlap, and prop some brush on em pretty easy for a quick one, or go completely natural. I don't do it in the wide open. Slightly inside the 'woods' with a good shooting lane next to a trail. I like to make a single wall, with a limb across a couple trees to prop brush against. It's free and works well. JMO
