Can I Post From an iPhone on a Moving Train?

It's only letting me write this "excerpt," instead of the main text of the blog post. So let's see what happens when I try. I should go back now and write this as a "note" in case it crashes but I am too lazy. Feeling slightly sick from typing this on the bumpy moving 10:35 Amtrak from San Diego to LA. Seem to be writing in dying person's last words Twitter speak. First Comic-Con with iPhone. Much easier. Text friends all day. Still remember being at Con and having to run back to room all the time to check messages in hotel room. Posting now. Let's see if this works.
