Doug,
Nice thought about Thomas on the C&TS. However, the reality is that the infrastructure (# of motel beds, restaurants, etc) of Chama and Antonito conbined does not qualify for a Thomas event. I have heard they are very adamant about such matters. They have very tight rules regarding facilities available, everything from potties to trash pickup to Thomas retail. Their position on this is to ensure that when the hoards of young Thomas enthusiasts and their parents show up that a lack of motel rooms and first class restaurants does not leave the familys with a bad or unenjoyable experience and in turn reflect badly on the Thomas image. They are so tight on such things that the Thomas engine must have its "face" tarped when not participating in an event. Such are the vagaries of todays marketing world and a fickle public.
But, that being said, there is nothing wrong with the C&TS running some kid-oriented advertised events in conjunction with the Thomas events on the D&S. After all, some of the traffic has to come from the SE part of CO and northern NM. Just get them to detour slightly over Cumbres Pass. Maybe next year or the next?
