Can anyone offer some clarification on the regulation of motorized vehicles in this area? My wife and I noticed that many people are driving their vehicles up the Valdez Creek road that leaves the Denali Highway to the north on the east side of the Big Su. I stopped by the Gracious house and asked the store owner. He said you could drive up it as long as you aren't hunting. I have heard of people riding mountain bikes up the road to hunt, but I am wondering what the point is of riding a mountain bike up the road to hunt if people are already driving up there in vehicles. And if the people that are driving up that road aren't hunting, what are they doing up there. There seemed to be a lot of motorized traffic up that road for an area that is supposed to be non-motorized. What's the story? Can anyone offer some advice? Are people driving up to a certain point, getting out and riding their bikes the rest of the way, or what?
