Drury Bros would be a wealth of information. I would love to hang out on. . . err, I mean with Tiffany, but I think Lee Lakowski would be the true wealth of info. In regards to deer management and property management I think these guys would be right near the top.
Charles Alsheimer or James Kroll would be a great wealth of knowledge and interesting conversation on deer behavior.
For information which most of us could put to use in our realistic hunting scenarios, I feel John Eberhert would probably be the most useful. For hunting pressured areas and public land, this dude has got to be one of the most down to Earth and knowledgeable guys out there. Not sure he has any 200" deer, but he consistently gets on mature bucks in pressured areas. Not only this, but his knowledge on escaping the masses on public lands would probably be beneficial. Let's face it, most of our private lands get as much pressure as public anymore. Tough to get a place to yourself that has any acreage to it.
For a twist on things, I will throw out a couple names of people I think would be the least beneficial to talk to: Jackie Bushman and Bill Jordan. Don't get me wrong, they could very well be beneficial if talking about marketing or hunting outfitters/high fence operations. Outside of that they strike me as guys that wouldn't give us average guys the time of the day.
