I don’t think I read all of the book by Carl Sagan whom I saw lecture on Global Warming at Trinity University, but I like the movie based on it quite a bit. I bought the hardback and still have it but I think the movie came out before I finished the book and I never got back to it. I had enough to read for classes at the time as I recall.
Close Encounters of the 3rd kind involve contact so I wanted to work that in here too. Ha, ha
