Hmm, I must be shootin a quite ass bow (Matthews w/ 2 leeches and 4" merc filled stab) ...cuz I have had deer damn near drop where they stood from pass throughs....although I will COMPLETLY agree with the talk about shooting at an alert deer...I wait for a shot, either looking away or down...and prefer not to shoot alert deer...think smart shot timing and a quite bow are the key elements here.
