Just arrived today.  One word can sum up everything here . . . WOW.  The city so far is spectacular, but even better is the surrounding mountains.  They are really unbelievable.   My body is adjusting to the altitude.  At the moment I have a headache, itchy eyes, and breathing heavy after only walking.  It is amazing what altitude can do to your body.  I´ve met a fellow solo traveler from Germany.  We´ll be heading south to Tupiza tomorrow.  It really can´t wait to experience the train ride and the adventure of getting to Tupiza.  After a few more days, I´ll start to post some pics.  Take care!
