Planning the route

So many countries! We will probably pass trough 20 countries... And visas?! Now we're researching which ones needs visa, and which ones thats even possible to enter. And not in war... Trough hole europe will be pretty easy but from Turkey trough i.e. Iran, Turkmenistan, Kyrgyzstan, gobi desert and to Mongolia will be a long rough hell of a ride! This roadtrip might become uptil 2000 miles... Not bad ey!
