As a companion to a post last month on Jungle is "101" (a wonderful Cast Member perspective on Disneyland), I present a September 1964 photograph of a somewhat overloaded raft:
A couple of things to look for: The Cast Member in the foreground is wearing flip-flops. The raft appears to have taken on some water, attracting the attention of the kids on that side of the raft. And what's that guy on the right doing on the wrong side of the railing? Was he an uncostumed Cast Member? At least he's wearing shoes!
UPDATE: Major Pepperidge commented that the lady is on the wrong side of the rope, too. She is not, though the smaller sized photo is ambiguous. So, here's a close-up of our lady friend!
