NSTA in PORTLAND with MYTHBUSTERS

I must find a way to get to the NSTA Portland conference this year. I had friends who attended 3 years ago when it was at Disneyland and they said it was fantastic (also, where I learned about the Paper Roller Coasters used in camp this year) And, I've heard that the Mythbusters will be presenting again. I must go! I really hope I can find a way.
