No, no, no, no,,,,,,, that is not the sad part. The sad part is not going again, You have your picture to review, edit, organize, share, and stories to tell. And now that you are more experienced -- start planning the next trip. For me the saddest part or perhaps most depressing part of my trips is the wait in the airport for the departure plane -- that is truely sad ---- But by the time I hit the ground in Denver, I have reviewed and edited my packing list, same for the misc list, made notes for what worked well and what didn't, made a followup to do list, and have tentatively discussed the next trip. No date -- just the next trip. We may go next year or the year after or maybe in a couple of months as we are doing this year --- (long story) -- point is --- we know we are going, just don't always know when. That is the best part.
