Since reading your book ‘Being the Change’ earlier this year, I made the decision not to fly. I have just made a round trip train journey between Champaign, IL and Schenectady, NY. The trip was not easy – rough tracks, etc. We certainly need to improve train travel in the US. The trip was no less tiring than flying. At the age of 80-plus, I will do this as long as I’m able. I will fly only in the case of a medical emergency.
