Flat Earth - Gleason's Map Says No Sunlight Beyond 80° South

According to Gleason's flat earth standard map there is never any sunlight past 80° southern latitude, even on December 21st when the alleged south pole is supposedly at its brightest. This is why no one is allowed past 60° south latitude without special permission under escort, because it exposes the globe lie. Everything past 60° south falls under the Antarctic Treaty. There is no Midnight Sun in the south, only in the Arctic when the Sun makes its tightest circle over the Tropic of Cancer.
