Monty Python had a sketch called "How to Do It Lessons."http://www.montypython.net/scripts/howtodoit.php
I really know nothing about the DIE method or what it teaches, but when I heard about this method, that Monty Python sketch came to mind. I do know quite a bit about deer hunting on my own little 200 acre plot, and I've been deer hunting since Reagan's first term.
Let me give y'all an over-simplified view of how to nail a big buck:
1) Go somewhere where there are lots of deer that can be hunted. Where I hunt, there are lots of deer. B&C says there are 45 deer per sq. mile. My guess is there are probably more.
2) Follow the patterns of the resident doe groups in your area. That means boots-on-the-ground scouting and time spent watching the doe. These are your bait that you will use to lure the big bucks.
3) Be nice to your doe. Don't hunt them. Don't pester them. Don't threaten them. Let them get used to your presence.
4) Find a few places where the resident doe frequently go. Put up a stand or blind to observe them. Find where they eat. Find where they bed. Draw a line between the two. Your blinds should be along that line, where it will be most advantageous to observe them without being observed. You will know you have succeeded so far in your endevour, if you are regularly seeing doe come by and they do not spook.
5) Wait until the rut happens. Be in your stands or blinds watching. Be there as often as you can for as long as you can. As the rut cranks up, big bucks will come in to tend your doe.
6) Shoot the big bucks.
Now, as I said, I know nothing about DIE. However, I daresay most hunters get hung up on #1 or #2. By the time they think they are at #3, they are frustrated. They have no clue how to pull off #4. By the time #5 comes around, the woods appear empty to them because they've fouled up somewhere in steps #1 thru #4. As a result, they never get to #6.
Me? Look, I get a shot at the top buck on the place maybe once every couple years or so. Sometimes it's just that he's got a cedar tree between us at just the wrong time. Other times he just doesn't show up when I'm there, but I consider myself fortunate that I have that kind of result for what I put into it. I have a neighbor who hunts the Opener in Sept to the last day in January and does not have much better results.
