If i'm going to go out towing this on any more public roads, i better add in some more safety before the police notice and want to discuss things...
A jewlery thing (necklace spacer?), and some chain.
Now there's a magnet on bottom of the hitch drawbar. Snap the hitch together, stick the chains up and adjust slack. If i used 2 smaller weaker magnets i could do the chain cross better,
