Gemini: Agreed! Make sure Mr. Happy wears his raincoat!
Boredfukka: I sympathize with your taxi story. I don't speak Russian, beyond enough to dicker with the taxis over price. Lots of drivers are hard working guys, all are trying to maximize their fares. Like any stranger in any big city, you've got to have your guard up at all times, be cautious, act like you know what's going on. If you can get advance opinion from your hotel on a fair taxi fare, you'll deal from a secure position. Some advise only using official taxis with the "taxi" signs, and avoid the free lancers. Also, many internet Ukrainian travel agencies will make advance arrangements to pick you up at the airport and drive you to your hotel or even to another city; this is a very secure solution. Yes, the police are commonly looking for bribes, so you have to give them a wide berth and don't give them a reason to interact with you.
Martin: I had a similar experience at Kharkov's airport. Security pulled me aside into a private side room and searched my bags and frisked me, pretending to look for terrorist stuff, but not stopping until they made me open my wallet. They didn't speak English, and went to great lengths pantomiming that I should remove large bills from my wallet and place them into their ledger! I gave them 50 Hrivna, and pretended not to understand their pantomimes. They were pretty polite and a I was laughing inside just a bit! At all Ukrainian airports I now keep all my big bills in my sock, leaving a little bribe money in the wallet!
Yes Taxi drivers can be a pain sometimes, like some have said avoid, the ones on ranks at stations, airports or bus stations, theyre usually unliscenced, and a bit dodgy.
found out myself from past experience. Some just want you to come back to their place see what they have etc, others want you to meet the whole family. (had that done once or twice) Ive been lucky up to now not had any madmen picking me up. everyone is so friendly though.
to be honest it was lucky i wasn't in a rush to get anywhere thats the main thing you have to remember. Most taxi drivers assume you want a tour of the place. Strange to say most tourists do just that.
myself agree teh fee b4 you start your journey and remember payment on arrival. Same as any taxi ride in any other country.
also Law enforcement: Some are corrupt and on spot chekcs/fines are customary whatever they can get away with. Its not that big a deal.
health: b4 visiting best to get jabs for hepatitis A. B, C and whatever else teh travel beureau recommends.
drink bottled water, you will find almost everyone does or boil teh water first.
yes its customary to have stomach bug for 1 or 2 days after arrival but that is just a change in air/atmosphere.
ive visited fsu extensively. been to places like vkladivostok, moscow, odessa, st petersburg mainly and have visited some of the wild areas. I wouldn't say i'm afraid of travelling in FSU you just have to be sensible.
If you have a problem report it to local law enforcement and or embassy in teh country. they often have teams that work in the areas you have problems.
