Ask HN: What's the best way to experience “Silicon Valley” environment/culture?

Motivation: - I have lived in Bangalore (India) for last 4 years, and been to lots of tech, startup & product conferences, meetups, etc. One common phrase I have heard often is how things go down in "The Valley". Many lines from established folks have started with "Back in the valley...", and so on to arouse enough curiosity as to what sort of holy land is this place? - I had the opportunity to visit SF for 5 days for Elasticon in March'15, did meet a few interesting people but frankly couldn't really find much magic of the promised land... :/ - I am planning to do a personal trip again now for a week or two to just spend time to explore "The Valley" & see for myself what is it all about... Hence looking for suggestions on how to best utilize time to experience the magic that is apparently much more dense here than most other places in the world, and then plan the trip accordingly.

Brief personal background: - 27 years old right now. Masters in Economics (Minor in CS ...unofficial), then 2 years as data science guy/analyst at large bank, then career shift with 2 years as full-stack developer at a "Valley"-funded startup. Now trying to solve a problem in fintech space starting with India.

Thanks!
