I can confirm that Margo passed away sometime in 2008. I don't recall the exact cause, but I believe it was sudden. I didn't know him well, but we had a mutual friend and would often run into each other at the theater. I knew who he was through this board and was initially intimidated by him, since his knowledge base was so vast. In person, though, he was very warm and unassuming. Sadly, our mutual friend who first told me of his death has also passed. I don't think I'm violating his privacy to say that Margo's real name was James, and he was an attorney in regular life.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
