We're off to Atlanta

We thought we were leaving for Iowa on Saturday. Now we are leaving Friday morning. Why the change of plans? I really want to see the new Atlanta Aquarium. It just opened. And I don't think we'll have time on the way back to Savannah. So the new plan is:

Friday
- Get up around 9 am
- Return library books and pick up some snacks
- Drive to Atlanta
- Visit the Aquarium
- Drive to Chattanooga, TN and spend the night at a hotel (I found a good deal online)
Saturday
- Get up at around noon
- Drive to Jeff's dad's house and spend the night
Sunday
-Drive into Ames
