For our anniversary we went to the City Museum. It's one of the coolest things I've ever seen - endless exploring through tunnels and passageways and slides. And when I thought that the outside was cool, we went indoors where there were caves and trees and waterfalls and even a 7-story slide.
Since it is so hard to explain, I'll just post pictures.
And then, since the latest trend is planking, we got in on that. Cuz we're cool.
