As with any trip of this size our route is an educated guess as to what we think we will do. It is predicated on our preference for slow travel, warm weather (but not too hot) with a bit of light rain (keeps the dust down), break days (for the dog and our own sanity), and safety. We are leaving plenty of time for interesting opportunities as they may arise. If the situation changes we would try to go overland over the continent of Africa rather than flying over half. We have also left the shipping home location open as to somewhere in North America but likely not direct to Seattle as we want to drive back and flying into the city would be too abrupt of an end.
