Scarey and Puzzling

I noticed early on that the hitch pins on our tow bar tended to drift towards the outside of the toad brackets. If the pins were inserted from the outside in, that meant there would be pressure against the retainer clips, potentially causing them to fail. To make sure I always inserted the pins from the center out instead, I added directional arrows to the brackets with a permanent marker and clear coat. Now we can drive hundreds of miles with the car in tow, and the retainer clips never get near the brackets. The likelihood is that the pins would stay nicely in place while going down the road even if the retainer clips were missing, but I'm not planning to test that theory.
