Crane GPS?


    National Geographic says no, whooping cranes do not have an internal GPS. They learn their directions from senior members of the siege.
     Which leaves unanswered the question about how the original cranes figured it out. Maybe they had the GPS?

    A siege of cranes?

    That's also an appropriate name for the governor and legislature. They've got us under a seige, for sure!
