Bolt burst into a trot. Sam's heart jumped down his throat. Up and down, up and down, he bounced in the saddle. His feet flew out of the stirrups. The fence and then barn and Grandpa flashed by. "Whoa!" yelled Sam. "Whoa!" Grandpa stepped in front of Bolt. He grabbed the reins and pulled Bolt to a stop. Sam took a huge breath. "I'm getting off!" he said. He slid off the horse. It was a long way to the ground. His legs wobbled. He thought Grandpa would be disgusted with him. But Grandpa looked pleased. "Not bad for your first time," he said.
