Went from 45,500 words to 55,000 -- an addition of almost 10,000 words. That takes the novel from 53% complete to 64%. Under normal circumstances, it would take me between 5 and 10 good days of effort to add that much quantity.
13 hours from Washington DC to Ethiopia (plus more just getting to Dulles airport), and a 17 hour return trip (plane stops in Rome to refuel) certainly provides plenty of time for writing, even if you are tired.
And I could have squeezed in more if I wasn't helping to take care of a child on the return trip.
