One of the biggest questions in California is about something called free right turn. Many larger intersections have right turn lanes that are separated (channelized) from the intersection by a traffic island. These lanes rarely have signals or signs directly associated with cars in the lane. The confusion comes from how to use the lane when there is a red light in that direction. In most cases, a right turn is allowed on a red light only after a full and complete stop. However, when there is a separated lane, the car may treat it as a yield. In other words, it's OK to precede on a right turn as a yield on a red light (if safe) for separated right turn lanes.
Here's the funny part. There is no law on the books in California that actually make this declaration, as far as I know. The free right turn rules seems to come out of the same absence of law regarding the requirement for a stop on red for those lanes. It's important to note that this rule only applies if the traffic signal is after the segregation of the right turn lane (which does make sense).

After a lengthy ride on a bus (with a driver that was more than happy to tell her personal story of how she and her husband ended up in Alaska), our tour group arrived at a small dock in Auke Bay. The tour boat had a heated cabin. We took off from dock and headed out of the bay.

At first, there were no whales in sight. As we headed north, we began to see spouts of water off in the far distance. The crew finally got us near some humpbacks. Over the next couple of hours, the boat went from one area to another trying to give us a glimpse of the whales. As the day progressed, we had better sightings.
Near the end of the tour, we watched excitedly as a whale lunged out of the water to fill its mouth full of fish. That was an impressive sight!
As we headed back to dock, I asked Allie's mom how many whales she spotted. She excitedly held up her hand showing all her fingers and said, "FIVE!" with as big of a smile as I've ever seen gleam. Everyone had a lot of fun on this excursion.

NASA and Goodyear teamed up to develop a "spring tire" that can bare 800 lbs without air. It is designed for Lunar and Martian exploration. The tire is more energy efficient and won't blow-out (which sucks on Earth, but would really suck on the Moon.)
CEMS Systems now has a portable fingerprint reader, useful for roaming and ad-hoc security checks, such as construction sites or bus boarding.
Remember those obnoxious jerks that used to walk around city streets supporting a loud boom-box on their shoulder? Well, there back! Here's an invention that tells the world that you just don't care about other people around you. It's the Stereo Neckphones!
