I will travel by train and by bus between some of Eastern Europe " contruy inFeb 2008 please advise?

Wear dark clothes that don't make you stand apart from anybody else. Don't look like a tourist, that would be my main concern. Don't bring out a dictionary for english-russian unless ur in a big town, because u will be seen as a tourist. However I would ask around if u had a question about something, to somebody who looks friendly.
