Apologies, Obiter: Moldavia is actually part of Romania. It's the territory between the Eastern Carpathians and the Dniester river. Moldova is on;ly slightly further east and stands as its own autonomous territory.
Atalanta/Black Cat: I'd love to go back. Unfortunately, airfares average circa £600. And after travel costs to the airport, overnight accommodation, etc., I'm afraid the whole thing would become an exercise in futility. My hope was to have the funds available so I could do something else with them. And at present, I'm spending more time in the Ukraine than originally planned. (and just in case anyone suggests it, I would most definitely consider carrying the Leu into Ukraine, especially in light of current circumstances).
I did, however, carry the Leu with me to Moscow a few weeks ago. I had gotten it into my mind that I'd definitely be able to covert it at one of the many black-market cash shops. However, I was sad to learn there were some currencies they simply didn't want to mess with, especially right now. Currently, Mother Russia is on the brink of kicking all the poor Moldovan workers out of the country, as retaliation for Moldova moving closer to the EU. It's a nasty situation, especially for the poorest country in Europe.
I think of all the suggestions, the ebay route may prove to be possible....
Many thanks to all of you for your kind and creative suggestions!
