San Juan=Cascade Canyon

Got me to thinking last night, but tourists dont particurally like cold weather that much, at least most of them. They all get mad when I rode the Winter train and opened the window the whole trip when I was 14. (or last summer, when I was the only person riding the platform on the WP&Y).
Anyways' it got me to thinking, how about restoring the San Juan Cars to their former glory, with the doors, it might help them keep a little warmer during the winter as long as I dont open the window (i'll move to the gondola). Plus it's an added bonus for railfans. The only problem is that there only about 4 (is that the #?) of San Juan cars on the D&SNG property, so they would have to make due with only a partial train.
