I'm looking forward to following your trip.
I do have one recommendation. Do your trip report in the Ride Reports section of Adventure Rider. I am on several forums and have looked at numerous blogs. I have yet to find anything that remotely compares to the ADV ride reports. For a trip like yours, getting a few hundred thousand hits on a ride report, if you do a good job, is not out of the question.
I ride, Therefore I Am.
