I'm excited about going to Eastern Europe. It is very timely. The current Euro exchange rate is 1.22 to a dollar. Time was when (during my Barcelona trip, 2007) the rate was Euro 1.68 to a dollar. I have to rewire the way I note down the dates: day/month/year; learn how to tell time by the 24 hour schedule, and when accounting for money, to convert all decimal points into commas.
I read about the history of Hungary, how they were part of the Austria-Hungary Empire, how their geographical areas were redistributed after World War I, and how the country's borders shrunk in World War II when it joined the Axis powers and Hitler lost the war.
