Yep, I know more about Mars than they've ever allowed us to know about Antarctica.

1.The Pieri Reis (sp?)map shows Antarctica without it's ice.
2.Some people think Antarctica was Atlantis...if you imagine the Earth spun around with Antarctica where the mid-Atlantic is now it makes more sense...pre-pole-shift.
3.Some scientists say the snow/ice cover is illogical...it shouldn't be possible.

I personally believe there are cities under that ice...and TPTB KNOW it. I mean long-dead cities...not currently inhabited ones..lol
