Barack Obama - Inauguration

Today I am staying home from school.  My mom wants me to be a part of History in watching the first African-American become our President.  I am very excited!  We have been watching TV all morning.  WOW!  There are a lot of people in Washington DC.  They are showing lots of time getting everything ready for this swearing in!  When is this going to take place anyway?  If I was at school, I would have missed it!  We are almost getting ready to go to lunch, if i was at school.  

How long is this going to take?
