On the road again: Las Vegas, day 4

I went to bed late and felt horrible as I crawled into the sheets.  I felt worse when I got up for good less than five hours later.  I've lost most of my voice to drainage, and tomorrow night is our big annual work celebration, at which I must speak, so I have a very short time to heal fully.

Consequently, I'm crashing.

Over the coming days, I hope to catch up on my Vegas report.
