It is an interesting subject. I hunt public lands, public lands everywhere I've hunted requires you to stay on established roads, they might not have seen a grader since they were established but they are still designated roads on public lands maps. I don't hunt big game.any longer just birds and preds.
I don't just hunt around my home.place but have killed.preds and fowl in NM, MN, SD, MN, WA, MT, NV, WY, CO, AZ, WI and have never bemoaned the fact that I don't have 4x4.
I recently bought a MC to hunt off of not for the ability to get places my van won't go, but for the ease of hiding it and the 60-80 mpg.
