Did you go to Mui Ne? Even more so!
No, cripes sounds like you wouldn't be able to move for them.
I've heard the Russians you meet on the trans Siberian are the opposite though, very accommodating and they ply you with vodka. Not sure if some have an ulterior motive though. I only did the Beijing to Ulaanbataar leg because I couldn't get a Russian visa.
My other experience of Russians is seeing England fans get jumped by them in Donetsk on the way to the England v France game last year. "We are the Russian hooligans" they declared.
