C&TS - D&S = Finally!

I have a deep, dark confession to make... I've lived in Colorado pretty much my entire life, and I've never ridden on either one. Yes, I know, but, you know, life.

So, my 55th birthday is coming up next week, I have vacation planned for the first full week in June, and my son and I ARE going to go ride both. I wanted to do them a day apart, and perhaps do something in between, my son is Autistic, and I don't want to overload him.

So, best advice, which day, which train, which cars? Etc? I'd prefer to ride in "original" wood cars rather than the steel reproductions, my son is 12, so he's eligible for the "Kids ride free" on both railroads.

Any advice, recommendations, do's, dont's, etc?

Thanks

Robert
