Too much coffee

I did not nap because I had too much coffee at breakfast.  It was worth it, though.  Since it is pouring rain, I've decided to join my mother and aunt on their trip to the Viking Ship museum.  I'd like to see that again, and I wanted to buy a book for my friend who is a 5th grade teacher.  She's doing a unit on the explorers in the fall and asked if I could find something for her.  I think I know which book I want.
