North America was first populated by migration over a land mass that is call Beringa but no longer exists. What is there now is the Bering Strait. I am madly in love with history, specifically Canadian history and this is part of where it starts. It amazes me that there was a land bridge there and I just want to be in or near that piece of history. Also, I once watched a documentary about attempts to put a man made bridge over the straight. THAT amazes me even more. People who migrated by foot over a land bridge have evolved to recreate what was once there so that we can trave from one continent to the next with out leaving the ground or having to go to sea. I love it!
