Why is Bud excited at the end of the story?

In Bud, Not Buddy, by Christopher Paul Curtis, Bud comes to the end of his journey, in Michigan (in the middle of the Great Depression) looking for his father. Bud (only ten) has lost his mother (at six years old). Since then, he has lived in an orphanage, and has been mistreated by his foster family and has run away.
