I once fell asleep on a Munich bus late at night (probably Oktoberfest had something to do with it). When I woke up, I was the only one on the bus and had no idea where I was. I started walking, and about two hours later, I was turning down my street and heading for home. I don’t know how I found my way, especially with the effects of Oktoberfest still snarling my navigational coordinates. So it is more than a little annoying that on this trip, armed with GPS, Google maps and my own documented capacity for finding my way in the middle of the night, I could not find my way from the train station to the hotel without a lot of gesturing and pointing on the part of the locals, and in one case, humiliatingly forced to take a taxi about eight blocks.
