Thanks to each of you for your comments and encouragement.   I also can't imagine HOW they do it.  But they ALWAYS have a big smile (no matter how much it hurts).  You may notice in one of the last pictures there was a bicycle wreck.  Actually two bikes went down.  After the show, but before all the guests had gone, a manager came out with the girls who had crashed.  He made them ride around a few times.  They were not smiling, but barely holding back tears.  I wasn't cold-hearted enough to take that picture. Lin, thanks to your comment on the music, I fixed the music timing problem (in my 'home version').   lw
