Tom,in my opinion not only the cheapest but one of the most effective blinds is a do-it-yourselfer,using the natural foilage around your hunting area!Year round on my ranch's I guide on, I build natural blinds primarily for gun hunters!As you know turkeys frequent the same areas throughout the year and a well placed natural blind can put you right in the middle of em!With a good saw,a pair of clippers,you can fashion exactly what you need and want according to what the birds are doing!I've hunted out of the same natural blinds for years and add a few limbs and what not year by year to keep them from looking like a big brush pile!Ya it may take a little muscle and sweat but you cant get any cheaper and I like being creative!The other advantage I like is when I leave the blind it stays,know folding up,breaking down,and hauling around the woods!Just an idea that works for me,hope it helps.....Bob
