What to do on Cal Day?

Hey everyone! As an EECS major at Cal, what are some ways (or some of the best events to go to) to make the most out of Cal Day? I read that I should try and go on some housing tours fairly early, but after looking at the engineering events, they all seem to start at the same time as the housing tours. Does anyone have any suggestions? Thank you!

Whenever I visit my son at Cal I like to go to the top of the Campanile (the view is great) and get a hot dog from Top Dog.
