From Pakistan into China without guide
I just left China via tha Karakoram highway with my Chang Jiang. One of the things I learned in China is how to enter China (legally) with your own motorcycle or car via the kkh. No chinese guide needed! But it is still not cheap.......
If you are interested you can contact me via firstname.lastname@example.org
I may not answer directly since I am still travelling in Pakistan on my motorcycle and will not arrive home before the end of November.
