We were among the first 50 or so people into Machu Picchu in the morning and the fog completely set the scene. It really made you feel like you were in a lost city and helped you understand how it could have been lost for so long.
One of the main reasons I love Miami is Wynwood District. The area is an ever-changing canvas of graffiti and social commentary. What was new yesterday may already have been re-purposed/-tagged/-painted today.
