I have the details somewhere of a company that run the very trip I mentioned.
It can only be done on a motorcycle and they us Enfields its quoted as a trip on the highest road in the world. I quite fancy it but Jan did'nt want to know hence our motorbike trip across Thailand and Burma next month. Mind you it looks pretty rough not for the faint hearted.
You have just reminded of something and i put a post in the M6 thread!
If you like your old bikes you need to take a trip to Kirkby Stephen!
Theres an old guy there has the most amazing collection of bikes i have ever seen!
If i remember rightly his oldest car was dated 1889!
