\Today's start through a tunnel. Tunnels can be good because it usually means you are going through the mountain and not over. A couple of times yesterday that was nice.
These things are found on the side of the road throughout the DMZ. What are they? Well they blow the tops of them off so they can quickly block the road if need be.
A fence line on the DMZ on the steep climb from yesterday.
Coming off the decent from yesterday looking at it. You can see the road on the side of the mountain. Pretty awesome.
You also see this on the side of the road in many places. See not joking.
