I'm sure most people passing by assume that this leads to a private building entrance or someone's office, and in part they would be right; the park is actually a "quasi public" space meant to serve as open space for some adajacent apartments, as well as a park for general use.
It's not too inviting at first, but go a few feet further and suddenly you're presented with this:
And this!
I think it's these kind of surprises that make walking such a great mode of transportation. There's a sense of discovery that you just won't ever get with a car (because you go to fast to take in the finer details of a neighborhood) or even transit (with its set routes and rigid schedules). And in the interest of promoting that kind of exploration, I'm not going to tell you exactly where this park is. You'll just have to take a walk and find it for yourself.
