Maybe as his interest started to go away, i would have tried putting some excitement in my calling, that has worked for me in the past. I have had similar experiences after the tom sees my dekes and looks at them if they are in full view, because okf this I try to put my dekes in a thicker or partially concealed place, since then I have been experiencing more luck, sometimes i wonder if they see the dekes and the lack of motion turns them off.....just a thought.
