Just wondering how you guys put up your Posters on your land. Galvanized nails have been used for years by all land owners. Has there been a switch over to Glue or String that I missed to save the tree. Sure, screw steps do go in deep, but like was said before, If the landowner doesn't want anyone to use them or build stands in the woods, then you do what you have to do. Use a tree climber, pop-up tent, stalk, whatever, just keep the landowner happy.
