Back in Colorado

Hi. After 18 hours of travel, I am finally back in Colorado and, as you can imagine, I'm very tired. I see that I received quite a bit of class-related e-mail today while I was off-line but, unfortunately, I'm too tired right now to respond. So, I will try to send a response to class-related e-mail tomorrow morning before class... and if I don't make it, I'll take care of any stragglers after class. FYI.
