Predators look a certain way and move a certain way. D didn't look or move the part. Scent didn't change though. In that setting, the deer are used to seeing people close up. In the wild you would still need to watch the wind.
Maybe that is a new experiment for this year. Can we do it ? Plain board, colored board, board shaped like a cow, board shaped like a T Rex.
Report back with your findings in October 2013. Heck, maybe sooner if we don't carry our bows at the time we do this. Either way it sounds fun.
