There is lots of road hunting where I hunt deer here in CA. The property is mostly owned by private timber companies so they have roads everywhere it seems. It's pretty rare to see someone out walking/still hunting due to dry conditions as we are hunting in September but you'll see the occational "natural" ground blind every so often.
I have been very lucky in that I have gotten to hunt Utah and Colorado for either deer or elk over the last 30 years. Everything in those states was/is walk, walk, and more walk, but I still love it and look forward to this years trip like it is my first.
