When I travel out to Mendi, I usually ride in a pmv (bus). I do this for a couple of reasons. One, our vehicle is not able to handle the rough roads between Hagen and Mendi very well. And since I don't have money to constantly fix it, I just don't drive it out that way. Two, most of the pastors and church leaders that we work with have to travel by pmv because they don't have vehicles. I do my best to try to work under the same restrictions or conditions that they do, so that I can relate to them better.
That is what you call traveling 'PNG Style', and I happen to love it! If you ever make it over to PNG some time and want to travel with me, I will gladly take you along!
