I love the new version. Each draft has gotten better. I don't have any more notes on the story itself, but I can't remember if I brought this up earlier: You do know that William Harrison is the name of one of our worst presidents ever, right? The guy got sick at his inauguration, laid in bed for a month, and became the first president to die in office (there's a fascinating story about the Curse of the Prophet that I don't believe a word of, but love telling). Anyway, just something to chew on; I don't think it matters too much, especially since most people don't even know about presidents like James Madison and Martin Van Buren.
Also, there are still a few typos that I know Trib will catch, but it might make his job easier if you can fix them: There are two places where is says "is" instead of "his," the words "fingernail" and "treetop" should be compound and not separated into two, and things like "four person" should be hyphenated.
Other than that, it looks great!
