I guess I don't see that as being the same. A fence put up so a deer can't jump over it and is forced to be contained is different IMO than a mile stretchof highway that a deer can cross and go wherever it feels like going. Yes a road may (or may not) funnel deer, but a lot different than a blockade.

I can understand how you can make your argument with land size, it's still an enclosure and put up to contain deer to me though. If someone owns that much property they can't have similar quality deer through management without putting up the fences? I disagree with that.
