"It was late when the boy said good-bye to the sign painter. And as the last bus came around the corner he softly said to the empty street,"
Just passing by...
A young boy looking for work gets hired by a man to go to paint a dozen billboards.
They work in the desert painting billboards. They only paint one word, ArrowStar, and a lady. The boy wants to paint more, a mountain or even a cloud, but the man says no. They wonder what ArrowStar is.
A man in a white suit had a dream for ArrowStar, a roller coaster. The sign painter says dreams come in all different sizes and asks the boy to stay and continue working with him. The boy declines and goes off chasing his dream of becoming a painter.
