Post w Voskresenskoye, Saratov Oblast, Russia

Hello, we 2 guys are heading to the world cup in Russia, we are also planning to visit Saratov. We are coming from Moscow by train or plane and wonder if it's possible to rent a car or what's the best way to get from Saratov to Rostov.

Waht's a must see in Saratov? We are curious about the memorial park as we have interest in the second world war.

regards

Dimitri
