Trivial Tuesday

Good evening.  Because I guessed a couple correct in Babybull's question last week, I was allowed to come up with the category and question for this week.  This week's question is in the category of Alien's trip geography. I am in Hannibal, MO, the birth place of a famous American author.  Who is it? Not much at all is going on.  The work is progressing at a good pace and I'm not rushed to get it all done in one day.  I will be here for the rest of the week and my flight is late on Friday.  Have a good evening.
