Go Bears! is more than a cheer, but a mantra to live life by…as long as you're a Berkeley alum like myself. On Saturday April 18^th, the University opens up to the public…lectures, interactive events, tours, all of the campus museums (most of which aren't usually open to the public)… and it's all free.

Many programs are geared for incoming students and their families. However, there are a few gems designed for everyone. This year's highlights feature hands on physics, discussions on energy & environmental issues, with the search for extra terrestrial life sprinkled in. For a complete listing of events, check out the Cal Day website. Here are my picks:
