Recently the Nazca lines got a nod by Dr. Jones himself in the new Indiana Jones movie (a movie which also could not have been awesomer [or "more awesome" for those who cannot accept the ever-changing face of language]). The lines are pretty impressive if you consider when they were made over two thousand years ago and interestingly enough it’s hard to tell what they are without flying over them. You tell me who was able to fly two millennia ago.
You can also check them out for yourself via Google Maps: HERE
How cool would it be to see them in person?
