Trades.
I am on the web (snowed in), and I checked the forum planning to add a link to an announcement that my Nephew (Dr Lee Berger)is coming the states for a few days this month. He is an interest guy. Still I will put a link to the announcement. Amoung his stops is to do a lecture at the Smithsonian. I love to debate him, even though he is younger than me he keeps up pretty well.
While here I read your post, and have to say I like your response. Like your other work it is top shelf. Well said my friend.
