Saturday the 22nd of March 2003- Day 32. Left Buenos Aires at 12.45. Massive Retiro bus station. Got there by metro (0.70p). Very hard to find the right loading bay. There are about 80 bays here stretching over 3/4 of a mile. Thought I missed it, but it arrived late. 20 hour bus jouney in sem-camba bus. Not as nice…
