They know that. That's why they're there...
Tell me about it... Last winter I tracked a nice 14 pt buck that hangs around the housing area...I tracked him for two days,he never got more than 200 yards from a building. Even when rutting does were around, he wouldn't follow them out of the "safe-zone"...(bow hunting is allowed on Mainside, but not within 400 yds of housing)...They have deer here that live for years and never venture out of "sanctuary"...
