I couldn't fault these two on this leg of the trip whatsoever. They came up against some pretty challenging situations along the way (dealing with roadblocks, etc.) which they handled immensely well, going above and beyond their duties to ensure that the we got where we needed to be. Really impressive work.
Bolivia is the poorest country in South America and it showed. Many roads are unpaved. People subsist on a daily budget - don't work that day, don't eat. But, although the trip has some challenges - altitude, long, dusty transfers, road blocks and strikes around Santa Cruz, the sites are spectacular and worth a bit of discomfort.
I can't rate all three of our leaders (Kate, Jacopo and Noel) highly enough - they all contributed to making it a trip I won't forget in a hurry. I thought they struck the balance excellently between being absolutely on top of the day to day business, while making sure that everyone had a good time (including leaving us to our own devices at times). I'd like to give a special 'shout out' to Noel, who was an absolute pleasure to travel with, a fantastic laugh, but always a reassuring presence in the group.
