RE: NYSDEC is a joke
in general, they tryuse similar land uses to help them determine WMUs and then try and use easily recognizable boundries (rivers, highways, etc.) to mark them. For example, 7M (where I hunt) is so big because it is premoninatly rural and they have tried to encompass the large amount of public land in the area. I probably wouldn't hurt to split it in half, but it is the way it is. Other units may be predominantly privately owned, others may be based more on topography. They do have a rythme to their reason.
