Ever since I saw this TED talk by the artist JR, I have been a HUGE HUGE fan. His stuff is INCREDIBLE. I was finally able to see his art in person on Ellis Island!!! As a traveler, I've had many amazing memorable adventures in my life... this one day was so special and feel-good, and so close to home! It was a 4 hour walking tour of the abondoned Ellis Island hospitals, in which JR pasted photos of real immigrants from the past and created scenes through out the space that really helped set the mood while learning about the history of these hospitals.
