Read this excerpt from a story.

Juan coasted down the hill, gaining speed. He executed the turn toward the basketball courts with ease, adjusting his weight on the board. Up ahead, he could see Kev and Sean, but neither one was skating. They were slumped on a bench. When he reached them, he asked, "What's going on?"

"They did it, man. They posted the sign," Kev replied. Sure enough, a new "No Skateboarding" sign had been erected beside the basketball court.

"Not again. I thought this court was a good spot. It's not like we are damaging the asphalt," Juan complained.

"I know. And the pickup games never start until after 5:00. This court will be empty for another two hours," Sean added.

"Soon there won't be anywhere to skate in the whole town."
