Bolivia!

One of the first things that has struck us about Bolivia is how clean it is. Sure the roads are dusty and some amenities can be basic, but there's very little litter and the market floors are swabbed down with bleach throughout the day. 
We caught a train from Tupiza (where we rode horses through a canyon close to where Butch Cassidy and the Sundance Kid met their end) to Uyuni and were pleasantly shocked to find reclining seats, TV, a fan with built in air-freshener and a conductor who constantly swept the floor and cleaned the loos. Admittedly we were in 'exejutive' class, but at £9 each for a six hour ride, why not?
