Again, I must mention how technologically advanced this city was, as I^11
imagined it enough to make practically anyone feel like Rip Van Winkel. I was
convinced no one ever paid in cash; swipe-and-go or scan-and-go was the
preferred payment method. I presumed both paper and money would soon be
obsolete and it was no surprise to find Seoul, very fittingly, sported a money
museum.
I strolled the Cheonggyecheon, an 11-kilometre stream, right in the heart of
the city. It’s believed the river was rediscovered after a raised highway was
demolished. By then, the area was a peaceful and relaxing space featuring
stacks of greenery, public artworks, wooden bridges, and small waterfalls.
