On my father’s side, I come from a long line of Norskes. After moving to San Francisco, I was pleasantly surprised to find a few more links to Norwegian culture here than I expected. (Not sure why I was so surprised since San Francisco is on the water and Norwegians are a notoriously sea-faring people.)
However, the best and biggest surprise is the Norway Day Festival at Fort Mason, where you can enjoy some great open-faced shrimp or salmon sandwiches and drink a few beers, all while taking in some fine musical performances and cooking demonstrations for things like lefse (a crepe-like item that you roll in butter and sugar). In addition to lefse, be sure to try some kringle for dessert.
Even if your ancestors didn’t roll with the Vikings, you can have a great time at this unique and fun festival. It usually takes place in early May. For more info, along with schedules for music and performances, take a look here: http://www.norwayday.org/
