The very best thing that happened was that my Husband brought my daughter. As you know, she has classic autism and doesn't like crowds, new places or loud noises. This particular event was a lot like hell for her... but she came and was so good and happy the whole time. It was a victory concurring fears for us both!
I also stayed a few hours longer and helped people learn to crack a whip. No one got hurt, so I'm saying that was a success too.
