Notice the wrench left hanging there on that lower shock nut. That could make for an unpleasant ride.

It's a good time to point something out. I forgot this wrench . . . you do NOT want to do that. But even if you are careful, it will happen. So always go back when you are finished and make sure you have all of your tools and every area of your project is properly cleaned up, bolts and screws tightened, extra fasteners and washers put away, tools removed, etc.

Some of us make a bad habit of using slots, grooves, holes or whatever as a tool holder. In this case it was left where it was used, but that wrench is dangerously close to the spokes. It could make a mess if it bounced loose during a ride and got into the spokes.
