I rather like the idea of not being able to enter a buck taken through an outfitter/guide service. Those organizations are set up in order to set you up on a trophy calibre animal, most even have certain minimum when it comes to the inches your animal's antlers have to meet.

Hunting on your private/public land you may only see one or two 110 - 130" deer, hunting on guided/outfitted land you may see several 130 - 160" deer.
