RE: Ghost bucks
If you truly want to knowyou must invest in lots of trail cameras. If you keep the cameras up year round, and move them around there is a chance you could see one of these bucks. Even the most paranoid of whitetails will make a mistake. If you set up on their feeding grounds and do everything right you could nail one without him ever seeing you.
Plus, we all know guys who take big monster bucks ever year. The reason these bucks get so big is due to nutrients and time. Most whitetails are elusive, but there are definitely some that are harder to hunt than others.
