I would love to get lost in a big city. Rohan and I recently watched the Bourne trilogy again and were both jealous of his international adventures, Tangier, Berlin, Paris...Amazing! (Having all that money would be cool also.)
On my to-read list is Dark Star Safari by Paul Theroux, based of his overland journey from Cairo to Cape Town. I would also recommend Emergency Sex and Other Desperate Measures, a look at what its really like working for the UN in troubled areas of Africa.
