Note: I was not at the competition myself. :(
Just recently, the National MathCounts happened(Friday, May 9th). After an exciting few hours, a champion was crowned. I'd like to congratulate Swapnil Garg for being the first Californian to win MathCounts with this question.
In addition, the California team won first for the third time in five years. Their coach was David Vaughn, who I'm happy to say is the coach of my school. In fact, I was on the team that sent him to Nationals, but Northern California had too many good people.
Congratulations to these people for winning MathCounts!
