I had my deerdummies up two weeks prior to the opener. When I climbed in my stand the evening of the opener, I could hear deer around me making noises I' ve never heard before. As I settled into the tree, the deer got closer and were still making this really wierd sound. When the group of does and 150+ scoring bucks got within 20 yards of my stand, I could make out their wierd calls - it was laughter. They started throwing sticks and stones at me. The oldest and wisest buck there, probably a 9 and a half year old deer - definite world record, explained that he' s seen it all, but THIS product was sure the funniest he' d seen in his long life in the woods of lower MI. So, I got rid of them and the deer quit laughing at me.
