Yeah I'm starting to realize how many things that I originally thought were mapped wrong are just outdated. Most of the NHD stuff seems to be. It makes things sting a little less though to know that it was the best they had at the time and was not as intentional as I originally thought. I'll have to keep my eyes out for more of them to update. 
I am with you on the park thing. It is kind of a nauseating color, even in small amounts. All the tagging of really large things in California that aren't parks, like protected areas, really doesn't help the matter much. I think a lot of has to do with making the map look "good" as much as vandalism. I've been trying to really hard to fix what I can of the park nonsense, but after getting threatened by an "artist" a few days ago for deleting the park tag on a national park, I've kind of moved on to other things. Hopefully you have better luck at it then me.
