Made a weekend trip to Truro, Nova Scotia to meet up with Ian Stott and several other tail draggers for a spirited drive on the back roads of northwest NS. (1,700 km in all). During the return trip home, I had a persistent rap coming from the rear. No lost in performance or signs of imminent failure. After resting from the trip I found the cause. Any guesses? Here's a photo of the destruction.
