Shit - seems you have succeeded in getting it all 100% wrong.
Must be quite hard to do this in view of the info and caveats in various postings!
Wherever you go, you must know that it is vital, if you do not know the area, to do some homework - your experiences reflect marvellously the virgin in the brothel - trouble is it seems that you did not even find one of these, either!
Anyhow - you screwed up but don't blame Riga or the Latvians - blame yourself - remember the Boy Scout's marching song.
Where is the next spot - Ulum Bator - now that's a real challenge?!
