It seems odd to go visit a big city and then spend so much time lounging around in a park. But I get a kick out of lying in the grass and seeing skyscrapers on the horizon. And the park is great for people sketching.
Some quick little doodles from the corners of pages..
And these musicians in the park.
I thought my son was taking a video of me sketching, but this is the video I found on my phone. Clearly the musicians fascinated him a lot more than my sketching.
