There is a carousel at the Yerba Buena Gardens in San Francisco. A few weeks ago, I went there:
Just ignore the fact that I'm not wearing any makeup and focus on the CAROUSEL! It's slightly less thrilling than when you're young and everything is huge and the idea of something moving both forward, and up and down, at the same time shocks your little toddler brain into believing it is some magical land of moving creatures... but it's still a carousel. It's still really fun.
