It's 10:15 pm the night before we leave. I have just finished the presentation. I wanted to show you how many computers and technology it takes to put a presentation like this together. There is one hour of preparation that goes into every minute of a lecture. I have 3 back up copies of everything and I am positive there will be at least one technical glitch along the way. But tomorrow I will be happily checking the list twice then we head out!
