sorry, i realized afterwards that you asked a different question. first, go north across the golden gate bridge. afterwards, you have two options: (1) you can pay for toll and go across the 580/Richmond Bridge or (2) avoid toll and take the 37 east. both the 580 and 37 will meet up with eastbound 80. you'll take 80 east toward North Lake Tahoe/Reno all the way to Truckee. Once in Truckee, take the 267 east and Northstar will be on your right.
have fun!
