What is it in humans that encourages many of us to want to take a hike? For some it is all about a destination, that dream vacation where you lie on a beach without any cares. For others it may be the comfort of a managed travel plan with various tourist stops along the way. But some simply have a desire to go, answering perhaps a call that is built into the genes. For them is not about the destination. It is about the journey. In many journeys, the traveler encounters borders. Some borders are marked. Some borders are not. Some borders are literal; others figural. Each page of Crossing Borders poses a question about encounters with journeys and borders with the hope of the reader to consider their own encounters in travels and even more questions. The format was inspired by an ecclesiastical book cover seen under dim light in the basement of the Mission San Xavier del Bac.
