No, that's not camera shake. The fog seems to make the more distant objects look blurry in the low-res view.
We did the standard 10-mile loop, counterclockwise from the northern entrance. However, we missed the turn back to the car and ended up at the other parking lot. Rather than head back down again, we walked along the road. In many places, a clear trail paralleled the road, but in other places it disappeared at a driveway and didn't pick up again until past a group of houses.
