I still have mine, and dare not use it for that very reason! Ditto a few other "riding mugs". A photo may be in order...
My Ozstoc Jacket with heaps of patches, and cap with badges, are both only brought out now for Ozstoc events. The jacket is beginning to fade from being worn on random rides, so there is now a summer and winter jacket to do the service the Ozstoc "all-season" one did for years.
