How did I miss this incredible tale of Andrea Barnes looking for the edge on a skidoo in 1961?

The following video was only just published in this past month. Before that, I've seen excerpts from the documentary but the publisher says this one is the "full one". It includes parts I've never seen of course, the most amazing of which is how the tale ofAndrea Barnes is told. What a fantastic tale it is! It's not directly related to my project of the perimeter mileage tour-- but it's so fascinating that I have to include it as part of our education on finding the true perimeter distance. Andrea Barnes was convinced that there was an edge-- and set out several times to see it! Alone! Or with limited crews and a little sponsorship. She did something like what Math Boylen is proposing with ropes and pegs, going across the ice to prove there is NO wall or edge-- only ongoing distance beyond the south pole. I suggested earlier that Math would end up like Andrea if he did so... and that's why I propose being a "keyboard explorer of the perimeter" to prove antarctica a rim, not an island. Anyway, here's a stunning tale... of Andrea Barnes from ONTARIO Canada-- my own home-province! I guess Andrea and I have kinship in a way now.
