Yes go and knock on the door to ask permission to hunt. If you get the wrong door usually the neighbors know the correct house to send you. I would knock before asking to hunt that day, maybe before season, if not at least a few days prior. Not required just what I do. That is for the places where you need permission first. As justgrad25 stated some areas are open access where no prior permission is needed because the owners live off site and granted open access for hunting. Waugh!
