What in your opinion are the must-see national parks? I've been to
>Black Canyon of the Gunnison
>Canyonlands (needles, pic related)
>Mount Reindeer
>Cuyahoga
>Bryce
>Zion
>Haleakala (the lower part)
>Sequoia (when I was very young)
>Grand Canyon (when I was very young)
>Mammoth Cave (when I was very young)

Also been to Dead Horse Point, which while a state park is totally incredible. I hope to go to Capitol Reef someday, but haven't been yet.
