Just covering my bases on this location because there's no easy angle to get a look. I'll check up a little higher where the lip juts out and then up high. I imagine you'd have to stand on the windowsill to get to that one. Both spots are marked in the photo.
Edit: I was thinking about the clue, "Imagine this is not a puzzle and you already know where the token is located. How would you go about retrieving the token?"
I'd like to search these 4 spots at Cartwright Gardens. The cracks in the rocks or possibly under the rocks if they are loose enough to pick up. Also, if not there, then I'd check the grate in the street.
Edit: my personal favorite is the third from the left, right in front of the tree.
