If I could go to any year, I would choose 1969. I would love to witness the first moon landing and be a part of that historic moment. I would also be interested in seeing the counterculture movement of the 1960s and the music and art that came out of that era. I think it would be an amazing experience to travel back in time and see a different world than the one we live in today.
