I really love the outdoors.  What national parks in the US have you been to?

I've never been to any, unfortunately but I heard Big Bend State park is really awesome.

I lived in Texas for a few years and unfortunately never went.  The scenery looked breathtaking though.

I'm from Texas and only driven through, never actually stopped to admire. I know part of it is in Mexico as well.

Are there any other state parks that go across the US border?
1_Wizard
I'm not sure about it. But something I do know about a national park is that Yellowstone was the first one signed into law.

Didn't Teddy Roosevelt have something to do about that?

I believe it was president Ulysses S. Grant who signed it. I'd really want to go there.

How many national parks are there in the US?
1_Wizard
59 as of right now I think. National parks are operated by the national Park System too.
