A guy who was a cop with me in the 60's came into a lot of money and bought two motor cycles for him and his friend...... they set off to try to go from England to China...... Before entering the Khyber Pass they were advised to get guns for protection against the many bandits... The bandits robbed them of their guns, bikes and just about everything else. When found they had to be repatriated.
A couple of years later they set off again to ride from one side of the US to the other on Harleys... they were robbed by a group of 'heavy' bikers who had seemingly befriended them and again had to be repatriated....... I have heard of many others doing successful trips but my friend never went on another.........
