Loren was determined he would take one American-made vehicle on this expedition, not a series of them; so in early 1979 he set off in another new AMC Jeep, this time a CJ-5. This particular expedition, however, was not meant to be. On this trip, I did not see Loren, in fact, I knew nothing of this attempt until five years later.

This, the third attempt, was brought to a swift and concise end in the Darien Gap itself. Loren had a rather unpleasant encounter with a somewhat corrupt Colombian Park official and would not agree to his "pay off" demands. As a result Loren and his other expedition members were allowed to leave but the vehicle was left deep within the confines of the Darien Gap, a long, convoluted story, to be told another day - A World Odyssey - The Epic Voyage of the Sand Ship Discovery.
