Stan, there's a "catch" in what Georgia requirements are to meet "normal agricultural practices". Certain methods of planting certain crops are permitted within specific dates. Some crop planting techniques are not permitted to be shot over after plantings outside "normal agricultural practices" and you are probably familiar with that more than most.
George, I heard an interview on the radio about a passenger pigeon book and I can't recall the name of the author. Among the many causes of extinction according to the author were the railroads and telegraphs which would transport the market hunters to the dense migrations. The telegraph would alert the hunters where to go. The barrels of birds were then railroaded to the market centers. The birds may be gone, but the places named after the pigeons still exist here in Georgia and throughout the southeast. Gil
