I enjoyed reading this again and recalling our chat where you first showed it to me. Your comment that "long" is very necessary here is certainly true. It really sets up the anticipation of the main event, which is sighting the butterfly. Again, it is not any butterfly but an "yellow" one, which are the most common and "domestic" variety, and generally don't command any special attention. Yet after the long pilgrimage this is a warm and welcoming sight.
