I had an opportunity to visit Delhi for work and managed to talk my driver into a day at the airport. It wasn't easy trying to make him understand the purpose and he was nervous, but we found a quiet place in a truck parking lot. The haze was horrible but the traffic made up for it :)
On the way back to the USA, I stopped in Europe and made visits to Amsterdam (where the weather didn't cooperate at all and I had to pay a four year old speeding ticket), Dusseldorf, Prague, Warsaw and Kiev.
Kiev was a real thrill with all the colorful aircraft plus the old Russian metal.
