Changes

Take the free bus from behind Tesco's to "Futurum Shopping center" (obchodni centrum). The Tesco´s is near the main train station, and the free bus has its stop right near the pedestrain bridge between the two big buildings. There you will find a gas station where you can ask, or just hold a "Wien" (Vienna) sign standing on the shoulder of the motorway. But take care, cars a going quite fast already. Instead of holding a sign for "Wien" you could try "Mikulov" as well. It is the last city in Czech Republic just right at the border. There you will find another gas station and also good places for hitching with a sign.
