I was in Sequoia National Park last week. All parking was absolutely full, people were parking illegally all over the place, traffic was slowed to a crawl because people were walking on the park roads trying to get to where they wanted to go, and there was a 45 minute wait for park buses because of a traffic accident.

We need more places like that, especially since we're becoming more urbanized, and kids are growing up without access to less-developed areas. Granted, there are a lot of unique places like Sequoia and Zion that can't be replicated, but every landscape has its own charms.
