I use mine here in NE Kansas. I don't like tree stands, dangerous, expensive and If I don't have any luck, I pack up and move. I know that they keep the scent down, plus I saw an article in mag that gave directions on how to make scent killer, I think it was 1 part Hydrogen peroxcide to 10 parts distilled water and some baking soda. I also spray around blind with apple juice. It has been successfull for me.
