So it is found near the sidewalk. Thought it was some skateboarder trying some flip and the board shattering on a curb. Wondering why not taken away to recycle the wheels, at least. Then seeing the symmetry. Not just thrown there randomly.
Somebody giving up the sport? Somebody taking away the sport from another?
Or some message that it may be trash, but it is neat trash…
