Our family was there yesterday, and we where amongst the crowd watching the video about flatulence. LOL! This was the very best festival I have ever been to, and it was free! There was so much to do - so much to learn. It doesn't matter what age you are. I teach Kindergarten, and I was thrilled to see Sid the Science Kid and the Magic School Bus. The crowd is big, but there is so much to do that you forget about the crowds.
