After finishing up at Kim Young-Sam's birthplace, we headed up the highway about 15 minutes to the Geoga Bridge, which includes an underwater tunnel portion, too. (See video below for "the experience')
Very cool for sure, and I don't mean to take anything away from the technological feat by mentioning that driving through it was a little underwhelming. In fact, after we'd gotten through it and ten more minutes down the highway, Myunghee asked me, "So, when do we get to the underwater tunnel?"… You'd think they could have at least painted fish shapes on the walls or something to create an ambiance.
