Along the Frontierland path on the way to Fantasyland, north of Big Thunder Mtn Railroad, you will see two photo ops. Now they are positioned behind railing a fair distance back, but you can get a picture of both vignettes.
The red wagon is parked about 3-feet from the railing and though one is not supposed to climb over, I DID! LOL
I was able to get a good look inside the Wilderness Expeditions and Delivery Wagon.
Growing up in Los Angeles in the 70s/80s we visited Disneyland on a regular basis and often after school, before "Annual Passes".
