I’ve not completely forsaken flying, but I’ve reduced it considerably. An analysis of my air travel for work concluded that I was flying much less than most while being one of the most productive scientists in my division. Since retiring six months ago I did fly to Spain (my wife loves foreign travel, which will be hard to give up), but have taken the train up and down the West Coast and will be taking the train to AGU and back (with my wife) this year.
