While looking for the best way to get to Turkmenbashi, Turkmenistan and back from Bishkek, Kyrgyzstan i ran into Flight Memory.
Yikes, i added all my flights and found that i have flown 8.5 times around the world and was in an airplane for 2.5 weeks. Just check the picture below or click on the FlightMemory-banner on the right 
Ok, so i am going to visit some stan-countries in central asia. The way to cross them is to follow part of the silk road. Do not have a route planned yet, but i want to begin in Turkmenbashi, Turkmenistan and end in Bishkek, Kyrgyzstan. The silk road is not just one route, but has several forks here and there. I want to visit Turkmenistan, Uzbekistan, Tajikistan and Kyrgyzstan. I guess i have to start applying for visas .
Below you can find some alternatives from wikipedia;
