I would like to warn hitch-hickers about way of getting a free transport here.
In nothern part of country - Bishkek, usually people ask for money for a ride, and if somebody is ready to take you in his car, please ask for how much first. Because you can be unpleasantly surprisi after you will want to get off the car, people can be nice to you but after ride they usually ask for money and for big money.
Foreigners tought local people to recieve money for every help, so for many kirgis people it looks normal.
They can also invite you to spend night in their house just to ask for money next morning.
In southern part there are lot of uzbek people who usually give you a ride for free, and kirgis drivers who go to Irkeshtam (Kirgis - Chinese border). In southern part there are no russian people and sometimes drivers know only basic russian.
Southern part is much more pleasant for HH.
Everything written above is more then correct.Kyrgyzstan is quite dangerous place and I strongly discourage anybody from travelling there with exception of southern part where is more friendly for foreign tourists especially alpinists but not much then northern.
