Interviewer: How long have you been a park ranger?
Rosa: For twelve years. I work in a national park in Colorado, high in the Rocky Mountains.
Interviewer: What do you have to do on a normal day?
Rosa: Every day is different. In the morning, I usually have to check the trails.
Interviewer: What rules do visitors have to follow?
Rosa: The most important one is simple: you must not feed the animals. Human food makes them sick, and it teaches them to come close to people. Visitors also have to stay on the trails, because the plants up here grow very slowly.
Interviewer: Do you have to work in the winter?
Rosa: Yes, but we don't have to give as many tours. Winter is quiet, and it's the best time to see elk in the valleys.
Interviewer: What do you love most about your job?
Rosa: My office has no walls!
