A dream of all geographers is to travel for academic research or job-related reasons on someone else's bill. Academic geographers, especially the ones at richer schools, can pull this off via grants. Another dream is to be the geography-equivalent of Indian Jones. Finding Nazi gold with lost maps, getting the girl, and adventure all are embedded in our DNA. Combine these two dreams together and one has a bad case of day dreaming Catholicgauze-style.
Well, this can come at a cost. Indiana Jones was denied tenure.
