We happened to be in downtown Long Beach today right at the same time as there was a scheduled meeting of the Queen Mary 2 and the Queen Mary.
The Queen Mary is moored at Long Beach permanently while the Queen Mary 2 was scheduled for a curtesy call - they came within about 1/3 of a mile from each other and tooted the horns. It was quite the spectacle and there were many people witnessing it.
Also - in preparation for the Toyota grand prix race in April the barriers were going up to make the street course. It was pretty cool on the way back - there were barriers on both sides of the street - would have made a great picture.
