14-Oct-2007 – The adventure comes from N°38 W°123.

Having fulfilled the 1st part of the mission, I returned to Point Reyes town and from there to the city of Novato. At this time no more fog was around. Here I once again was on freeway 101 but heading south and I soon changed to 37 (Sears Point Road) towards the east. When I arrived at Vallejo city, I stopped in a Denny’s restaurant at Sonoma Blvd. to have lunch, but service was very slow because it was full and I lost some time that I might need later. Now with energy reestablished, I continued on Sonoma Blvd until the interstate I-80 North and in a mile I arrived at interstate I-780 where I continued my way towards the east. Later I changed to interstate I-680 in a southeast direction and crossed the Suisun Bay.

Later when arriving at freeway 4, I turned toward the east and at Willow Pass Road went south. In just a few meters I started to see the fence that appears in the photos of all the previous reports with the signboard warning that this is a restricted area.

I made a U-turn and parked the vehicle. I walked with my GPS until obtaining the minimum distance to the confluence which is 50 meters. I took the required pictures and the 2nd mission was accomplished at 02:03 p.m., a piece of cake. The confluence is located 28 meters above sea level.

Once I completed the activity here, I continued with my itinerary towards N°38 W°121.


14-Oct-2007 -- La aventura viene de N°38 W°123.

Cumplida la 1ra parte de la misión de dia, regreso hacia la población de Point Reyes y de alli a la ciudad de Novato, momento en el cual la neblina desaparece. Aca tomo la autopista 101 hacia el sur y luego la 37 (Sears Point Road) hacia el este. Al llegar a la población de Vallejo me detengo en un restaurant Denny´s en Sonoma Blvd a almorzar, pero por mala suerte el servicio fue muy lento debido a que estaba lleno y perdi algo de tiempo que luego me podria hacer falta. Ya con la energía reestablecida continuo por Sonoma Blvd hasta llegar a la interestatal I-80 direccion norte por un par de kilometros y despues la interestatal I-780 por donde continuo camino hacia el este y al llegar a la interestatal I-680 tomo la dirección sureste y paso la bahia Suisun.

Luego al llegar a la autopista 4, tomo la vía con dirección este hasta llegar a la la carretera Willow Pass hacia el sur. A los pocos metros empiezo a ver la cerca que aparece en las fotos de todos los reportajes previos con el letrero de advertencia de que es un área restringuida.

Di vuelta en u y estacione el vehiculo. Camino con mi GPS hasta lograr la mínima distancia a la confluencia la cual es de 50 mts. Tomo las fotos de rigor y lista la 2da misión del día a las 02:03 pm, todo un tiro al suelo, imposible de fallar. La confluencia esta ubicada a 28 msnm.

Una vez de completada la actividad acá, proseguí con mi itinerario hacia N°38 W°121.
