I never stopped to think of the engineering that went into the construction. The check for loose rivets is clever in its simplicity. Compensating for the change in the weight of the cable by the chains is something that would have been easy to overlook. I'll have to look for the chains next trip. Thank you for an educational and entertaining 30 minutes.
