The Natural History Museum was just a few blocks away from where we were staying, which was awesome. I haven’t been there since I took my kids 20 years ago. It’s an excellent museum (aside from a very old bird exhibit that looked like it had been done a hundred years ago). They have a very good dinosaur exhibit. Some think it’s because of the La Brea Tar Pits, but that’s a misconception as the tar pits came later.
