No such thing as the October lull. The deer are still are around. They still eat and drink.
What happens is they change patterns. People always panic when they don't see all the deer on their cams, eating from the corn pile. The big secret to where deer go is....wait for it.....ACORNS !! Acorns are THE food to pack on the weight and gets the deer ready for rut.
It can be hard to find the deer because they don't have to travel far to eat. This year has an abundance of acorns so pinning them down can be tough but trust me...they are on the acorns.
By the way...killed my biggest bow kill ( 173 typical ) in mid Oct. going to acorns.
