You didn't find the only two suspicious ones. There's a cemetery marked in the middle of a neighborhood that definitely predates the gnis:created tag.

If you're familiar with this park, can you set the one-way direction?

Someone broke RCP since the last time I looked at it a few weeks ago, and I saw it in the list of affected relations in the changeset. It might not have been you, though.

Did you clobber Rock Creek Park?

Might want to add `access` tags to those toilets. Some maps make it look like you can waltz in and use the President's bathroom.

This is the most zoomed-out I've ever seen a changeset.
