What configuration do these grind turn bricks need to be in? Can you post an example? I can't get them to work properly, they just send me in the oppisite direction or dismount me. Like do you place them at the corners of a square or do you put them a block before the corner? I don't loving get it.
Also can you create a round spring yard zone- casino night zone bumper? You know, the ones that go PING?
