In Manhattan, NYC, and Hudson County, there are quite a number of parks and gardens… verdant, and full of people enjoying them. Some larger than Central Park even, and some little ones tended by local residents. Given that the largest cities land-wise in the US are in Alaska, we can’t compete with those open spaces. If you’re in an actual large city with over 1 million people and lots of square miles, that would be Houston, and despite the more “open” spaces, the car culture would be draining for me.
