Many, if not most of us involved in some way in the mid-to-late sixties and early seventies are in our own mid-to-late sixties and early seventies now. I, for one, will be lucky to still be around for the FORTIETH anniversary of #483 pulling the first C&TS train into Chama (in 2010), and very lucky indeed to still be around, and healthy enough to take part in the activities, for the fiftieth in 2020. Thus a certain sense of urgency ... Tom Gildersleeve has been retired longer than I have, and I believe John West also. Ernie Robart, like Roger Hogan, isn't too far behind.
As noted several times elsewhere, the goal of us Old Farts / Foamers / Curmudgeons trying to raise money for the restoration of #483 is NOT to raise ALL the money, just to raise enough to lower C&TS out-of-pocket costs enough to make her the cheapest (for the RR) and therefore the most likely next engine to rebuild.
