Ah, my pet peave with the gameless commission. Only answer I have ever heard that is a good one is....power. We hunters pay for the land but we are only able to access it when the folks WE employ, pay their salaries, give them nice vehicles, retirement, etc. decide to give us access. I have heard a whole list of bullsxxx excuses while they encourage private land owners to open their ground to hunters year around. Now I am ready for the apologists. What say you?
I think you're being a little extreme. You're able to access the land, just not always by motorized means. I know of 0 private land owners that allow the public to drive all over their land year round.
