What is it like being a park ranger?

I always thought that seemed like an awesome job. Or a zookeeper. Becoming a veterinarian involves way too much time in school (like 10-12 years, I believe). I enjoy nature and animals. I came across a park ranger eating her lunch on a hike a couple weeks ago. I didn’t want to bother her, but it seems like she had the best job ever. Since she worked at the park with the biggest waterfall in Ohio.
