I'm guessing writing a blog would be pretty parallel to a lone astronaut, on his way to Mars, writing in his daily "captain's log." I suppose he'd have much more to say about errant comets and random space "stuff" rather than blather like you're reading now. That is, IF anyone is reading this other than me. Now that begs the question, "If one writes a blog and no one reads it was I ever written?"
Chew on that one for awhile.
