I've been on more than one farm that had a Higgens consultation (don't think it was Don himself). There are some things I don't agree with in their philosophy, particularly on a bigger farm. Certainly more than one way to skin a cat and differing opinions arnt necessarily wrong.
As OP alluded to, they really push to congregate towards one destination plot. Where I think this hurts farms is you end up holding less deer. More food, more spread out, in theory makes it less predictable to hunt, however I think you can hold more deer, particularly more mature bucks. I am of the philosophy; the hunter only has to be right once so I am totally OK with the idea of hunting in one spot knowing the target deer may be feeding in another. At some point, done smartly, paths usually cross. I like my food spread all over the place where it makes sense, including fruit trees.
