One place to setout camp cars could be Toltec siding. You would not have to worry about much traffic other than the trains. It is also a very beautiful view of the valley. The siding is long enough that you could set out more than one if the business picked up. Or have a group camped out together in 2, 3, or 4 cars. Just an idea. I think I would be interested in doing something like that if it was available.
