Reading Bulgarian Background, by Bernard Newman. Travelogue published in 1961 about the authors journey though Bulgaria during that period. The two main monasteries, Rila and Bachkovo, sound like interesting places to see. One particular comment about a bicycle journey down the Danube has inspired maybe a holiday next year. Cycle tour though Austria and maybe a long term plan to cycle the whole way around the Black Sea. The later is definitely something that requires some planning.
Anyway the book is quite interesting, provided me with some insight into the Balkan history from the Bulgarian point of view.
