The train that is my California adventure had one last scheduled stop, and it was second only to the beach in epicness. The Computer History Museum in Mountainview was a place I could easily spend a week straight, and if possible I would consider living in it. The entire range of computer technology ranging from the Babbage engine to modern PCs was represented. All the "artifacts" were protected by only a rope, giving full unobstructed views, including that old electronics smell that permeated the building. A mandatory stop for any nerd who happens to be in the area.
