My four-year-old son is very interested in space. Last night, his mother read him a book about space. Afterward, he asked if I've been to space. I answered, "No." He asked if his mother has been to space, and I again answered, "No." When he asked, "Why not?" I explained to him that we are not astronauts. Even though neither of us work for NASA, and have very little chance of going to space, we are fortunate enough to attend SPACE this weekend.
Facebook/Twitter thingies when I'm there, seeing as how I now have a (used) laptop.
