Instead: SF is a stellar place to unwind. Do that.
Catch a Giants game. Drink fantastic coffee (Sightglass, Blue Bottle, Epicenter, Four Barrel, Ritual, etc.) Get a Chocolate Shot at Tcho, Ice Cream at Humphry Slocombe, a burrito in the Mission, and Shabu Shabu. Drink a cocktail at Alembic or Comstock. Spend an afternoon peoplewatching in Dolores Park. Shop at the ferry plaza. Walk across the Golden Gate. Take a few days of the best weather that you're going to see for the next 4 months and enjoy it outside.
If you're interested in learning, drop in on some things at Stanford and Berkeley - find interesting talks from people who are doing legit change-the-world research that you can sit in on.
