Warning: Nazca to Cuzco km40
Around kilometer marker 40 en route from Nazca to Cuzco some genius decided to resurface the asphault with something similar to gray marbles. Now, normally this wouldn't be much of a problem except they decided to start it at the apex of a turn (i.e. where you have the greatest lean). There is absolutely no warning of this, and it looks like regular asphault until about 10m ahead. So consider this your warning - be careful!
