Kent's link to YouTube has some problems, I think, and since Kent is on
digest, he won't know it for a few days, perhaps.  Here's a good link to the

I am so glad Kent filmed this moment--I had to leave to get to the final

If you want to see the other clips, you can find them from this place, or
search under "Arkent43."
