La Paz, the capital of Bolivia, is breathtaking - literally, due to its hills and high altitude. It is surprisingly modern and very beautiful. One site I will never forget is arriving on the edge of the valley at night and seeing the lights in the valley merging with the stars in the sky. It was amazing. We were there during a festival that had marching bands parading all day and into the night. My wife had to go to the hotel lobby at 4 am to get some sleep due to the noise.
