I had felt like being in the wonder land as Fr. Joseph and I traveled in Uyuni well known for its salt desert. During the travel, both of us severly suffered from headaches because of the altitude. La Paz, the capital of Bolivia, is located on the top of the Andes Mountain which is over 3,600 meter.
We took a bus for 12 hours to get to Uyuni and then drove a SUV for a couple of hours to get to the salt desert. It was spellbinding. I uploaded some pictures in my Flickr that you can find in the right column of the homepage. Just click the Flick sign to be in the wonder land!
