18 miles. I spent last night camping on Mt. Diablo. I rode the 22 mile climb to the summit yesterday afternoon and then came down to about 1000 feet to camp. The view from the top was as good as anything I had seen on the trip. I found a great place to camp with a view of the valley and bay. I dropped my bike off this morning to be shipped home. Around noon I took the train into San Francisco aind walked around town for several hours. My flight leaves at about 11:00 tomorrow morning. I'll wrap up the blog with some final thoughts on the flight home tomorrow.
