So Tired I Can't Sleep?

Well I'm in one of those rare situations for me where I am really tired but I can't sleep because of the anticipation for today's trip to Sydney! The fact that I have also been packing has kept me up too, of course. I leave from Boston's Logan International Airport this afternoon at 1:30PM. After stops in Toronto and Vancouver and more than 24 hours later I will be in Sydney! I think I'm finally ready and I think sleep would be a good idea at this point. I'll post again either later this morning or during one of my stops when my brain is functioning a little better!
