    Sorry we didn't have more time to debate but I told you I had to leave
    today. As to the above, statement, All I see is that you actually made my
    case for me about the Okefenokee being capable of replicating the features
    you describe. I fail to see how you miss it. You wrote prior to the above:

    I will.
