Nazca

Viewed tha Nazca lines which are perfectly formed geometrical shapes upto 135 metres long that were produced by the Nazca people. They removed the darker surface rocks to expose the lighter rocks below. They can only be seen from the air so how come they are so perfect and why did they produce them. For an accurate answer Google Nazca Lines. Took a 30 minute flight over them and these are some of the shots. You will have to look closely to see the humming bird.
On the way there we met a German also on an XT660R and it made me realise that mine is well down on power.
