Have you ever been to a National Park?

Yup. When I recently drove cross-country I stopped at the big ones and camped.

The ones I've been to are:
-Yellowstone
-Yosemite
-Lassen Volcanic National Park
-the Grand Canyon
-Glacier National Park
-Redwood National Park

I have to say, I think my two favorites are Yellowstone and Lassen Volcanic National Park. All that thermal activity!

I don't think so. What is a national park? Are you talking about the zoo because if you are, I have definitely have been there.
