As they hiked, Mary's mom pointed out different types of trees and flowers. Mary's dad told her about the different types of animals that lived in the park, such as deer and birds. Mary listened carefully, taking it all in. After a while, they came to a clearing and met a park ranger, who introduced himself as Ranger Tom. He was wearing a green uniform with a ranger badge and a brown hat. 'Hello there, I'm Ranger Tom,' he said with a smile. 'Welcome to our national park. I'd be happy to show you around and teach you about the wildlife and natural beauty of this place.'
