Looks like Delta is running a sale right now-- I was able to get some really cheap flights from the east coast to San Francisco through Yahoo for the weekend of the festival. I have never seen flights this cheap here!!
Damn! I wish I've seen this before, as there are flights from Dulles Airport for $205 round trip!
I booked a flight last week from Richmond, VA (which is actually an easier drive for me to get to) for $310, but I would've drove up to Dulles to save a $105!
