Just spent three and a half months riding China Kazakhstan Uzbekistan Kyrgyzstan and back into China.
Overstayed a visa in China and ended up staying on a moneychangers floor hiding from the police; attempted robbery and threatened murder in Kazakhstan; Stayed on a marijuana farm; Bribed my way onto the oldest medressa in Central asia at sundown; Got caught up in the recent Urumqi riots and arrested as a suspected journalist. Camped in the middle of sandstorms; stayed in yurts; lots of bivvying in the middle of nowhere; became incredibly ill a hundred miles from the nearest habitation and had to cycle; rode through snowy passes at altitude; Drinking from brown streams and puddles after running out of water; met lots of wonderful people, met lots of people who i never want to meet again. Was offered a wife in Kyrgyzstan; Invited into many people's homes; ate some incredible food and much more food which was awful. Was I believe in the last hundred people to EVER experience the ancient islamic city of Kashgar (due to be knocked down, and from what i gather still no access for foreigners). Rode the olympic cycling facilities in Beijing. Bivvied out on top of the great wall.
I feel bad that I came home, should have shrugged off all percieved responsibilities and kept going.
Go ride, you can always find ways to make money and keep going.
