I went to the Pageant of the Masters last year, for the first time. Aimee and I went again this year. It is an amazing event. Each year they choose a theme and select art work, paintings, sculpture, posters and depict them with live people dressed as those in the paintings. It is kind of hard to describe, but really worth going to. They have been doing it for 80 years and so really have the whole thing down.
It was a good two hour show, out under the stars. They also have a whole plaza with a high end art show, music and food. Worth the trip! It lasts about 7 weeks every summer in Laguna Beach.
