U.S. volleyball having its best Olympics ever

The U.S. volleyball teams have had an extraordinarily good run in the Olympics so far. There are four disciplines in the sport -- men's and women's beach volleyball and men's and women's indoor volleyball. The U.S. has a good chance to medal in all four events and might even win gold in all four.

One gold medal is already certain: the powerhouse women's beach volleyball team of Kerri Walsh and Misty May-Treanor won their gold Thursday morning in a rainstorm in Beijing.

I went to the women's indoor volleyball game that started a couple of hours later, where the U.S. indoor team upset Cuba in three straight sets. That puts them into the final.

Meanwhile, the men's beach volleyball team of Dalhausser-Rogers is in the final Friday in Beijing and the men's indoor team has made it to the semis. It also plays Friday.
