Dear Wayne - You are correct in associating those holes with the burrows of crayfish (also known as crawdads or mud bugs in various parts of the country). They are quite common in our area (SE West Virginia), and I have seen them at quite some distance from any visible stream or pond. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
