Inconceivable 
, that you should be upset after accomplishing a ride that many can only dream of doing. Your putting fingers to keyboard and giving me a description of the activities that day put me in the place of being the stoker on your journey. Thank you for the trip and please look deep within for the embers still smoldering and waiting to burst into roaring glory allowing you many more miles of pleasurable relaxation or muscle aching agony that awaits on the trusty steed.
A rethinking of future mileage awaits all of us as we age so please do not despair.
