In 2004, my girlfriend and I made a tour through Mexico. We crossed the country from Mexico City to Cancun, visiting tens of ancient Maya sites. We extended our vacation with a trip to Yavin IV, aka Tikal - Guatemala.
We didn't stop there. We have successfully travelled to Middle Earth and The Matrix.
-- UPDATE --
My Star Wars : A New Hope page has been updated with lots of Tunisia set photos and movie reference pictures. With many thanks to Mark Dermul, who organized 3 Trips to Tatooine (Tunisia).
