This was to be Srinath’s cross-country flight. However as we cleared the Livermore ridge, central valley was covered with fog. We flew over it for a while and then returned to Tracy for touch-and-go. As Steve remarked, every plane is equipped with a 180-degree turn so we flew over the fog layer for about 8 minutes and then turned around. Along the way, Srinath got some experience dealing with VOR, looking for landmarks, guessing locations of airports in the vicinity based on heading and looking for holes in the fog layer if we needed to dip down. A few average landings at Tracy gave him more practice.
