I read this story last Saturday over a few beers. I love this story, which I've read twice in the last month. It's slightly depressing though. I think it is a commentary how humans are slaves to technology and that technology is a danger to the planet. I wish he had given the reader a slight glimmer of hope at the end. I wanted to read it again because I was having a shower in the morning and the AC/DC song from the movie came on and I couldn't get it out of my head. Instead of morse code though, I wonder what the trucks would use today? Peterbilt and Chuckhole.
