Thanks for your feedback. I should have used a direct link, but Scribd made it easy to see stats and allow comments, so I caved.. The letters next to activities on the timeline match up with the places on the map. To avoid clutter I made the assumption that no letter = Canada. However, your comment makes it clear that perhaps this all should be more explicit, or done differently. Will have to work on it. Re: shades of grey -- what for?
