This is an awesome training tool for my kids! My 6 year old son has a globe and has NORAD's Santa Tracker on the monitor and tracking it on his globe. He's explaining the time differences to my 4 year old daughter and brought up "remember when daddy was in Afghanistan and it was morning, but it was night here?"
