Long term shelter for wooden cars?

Maybe this has been discussed before, but I don't remember it. While we're all highly appreciative and impressed with the restoration work of the Friends of C&TS (on structures and rolling stock a for-profit operator would have no use for), I'm wondering what the long-term plans for rolling stock shelter are?
It's great to see these old wooden cars getting restoration work today, but I'm wondering about the eventual time when the volunteers are too old to participate. What will happen to the equipment then? Also, there still are more cars than the volunteers can feasibly restore.
It would seem that a couple or three long, roofed pole shelters (3-4 tracks wide) could make a world of difference for this ancient equipment. Orange Empire Railway Museum in California just built a similar carbarn, capable of holding 65 cars. Theirs is enclosed, but one on the C&TS might not need to be. Open sides might make access better in case of fire. Antonito is probably better than Chama, as it is dryer and such structures would not impinge on a historic site.
These would not seem to be terribly costly to construct, perhaps using some donated broken telephone or power poles, local sawmill lumber and corrugated roofing.
