    You may take buses every day. But do you ever think about painting buses? In Washington County of Pennsylvania, US, there is such an activity for students.

It is held at the local fairgrounds (露天游乐场) every year. This year, it was held on Aug.17. Students from 13 high schools competed (竞争) to paint buses. The buses came from schools, churches and some bus companies. Each year the winning prize is $100.

The kids can paint the buses freely, but there are a few rules. They only have one hour to paint a whole bus. The pictures have to be about a theme. This year it was Star Wars. They can't paint inside the bus. Each school must paint with certain colours. Each school has to show its name on its bus.

The final winner was Avella High School. They painted their bus black with lighter paint to make it look like space. There are many Star Wars characters (人物) on the sides of the bus. The students all thought it was fun.
