Deer in some places may tolerate being bumped, but, we dont hunt an afternoon feeding area unless we can get in and out without alerting the deer. Our best spots are creek ditches and steep hillsides that allow us to get in and out even if deer are in the feild. These are mostly groundblinds we will start hunting this weekend for youth then bowhunt and mloader the rest of the season. Even though they are way overhunted they get better all the way untill the end of season. If you get busted everytime you hunt a feeding field it will burn out real quick and bucks wont show untill way after dark.
I would have to agree with your dad on walking the long perimeter way in with the wind. If the deer you are hunting smell you going in its over. Plus if you bump deer on the perimeter you most likely just push them into yours rather than off your property. I also like walking perimeters just to educate the deer to the border and danger.
