We took Eleanor and Edith to their first circus this past weekend.  It was the Piccadilly Circus.  There was an elephant.  That was pretty much the extent of the excitement as far as the entertainment.  We did get to ride the elephant which was weird.  And after having recently watched the documentary "The Cove" I felt terribly guilty for having supported the whole wildlife as entertainment issue.  Anyway....
When asked what her favorite part of the circus was Edith said "the elephant, the part when the elephant pooped".  LOL  So there you have it, the show review of an almost 4 year old.  Eleanor did so good at the circus.  We had to sit her in the stands with us to get better then handicapped seating.  We left her wheelchair with all the strollers and carried her to see the elephant and had her sit between us, in her own chair, during the show.  She did great! 
Edith came home with a large inflatable pink dolphin which she LOVES!
Here is a picture of us riding the elephant.
