There are some pleasant aspects to parking in Russia, however. Parking fees are not usually charged in Moscow, and with the exception of some roads, you can leave your car on the roadside for long periods of time. Exceptions include airports, paid parking lots in front of upscale shopping malls and along the side of some very important streets, such as Tverskaya, where parked cars are quickly taken away by tow trucks to be impounded. Do not be surprised, however, if in smaller towns a young man approaches you and offers to keep watch over your car for a small fee. By accepting the offer, you can be sure that hoodlums will not mess with your car while you are checking out the sights. When you come back to your car, you may be pleased to see that it is not only safe, but freshly washed as well. It is up to you whether or not to pay for this extra service.
