At small town Baptist church in Louisiana, back in the 60s, we had an elderly preacher filling in for our regular pastor. He made a comment about the Bald Eagle as the national emblem. He believed that more thought should have gone into the selection process. For example, if the eagle and a crawdad were on a train track and the train began bearing down on them, the eagle would fly off whereas the crawdad would turn and fight to the bitter end.
