Today's mountain pics are all from the pre-digital era though I don't believe any of these are particularly old. I think they all come from the mid 90's up to about 2002 or so.
Look at that line. I can distinctly remember right after Big Thunder opened and waiting in lines like this only to get inside and see the queue going on for another 14 miles or so.
You know this is a pretty old picture because there's a Keel Boat traversing the Rivers of America just to the right of Big Thunder.
This was probably taken from Fort Sam Clemens on Tom Sawyer Island.
