So this concept initially blew my mind. I have been in Daejeon for two weeks now and since it is currently the rainy season, the river is starting to flood. While on my morning run, I came across this same dam, but you can no longer see the stepping stones and the river is flowing so quickly that there are rapids engulfing the whole dam. What makes it worse, is that there was a grown man still attempting to cross the dam! The rapids were crashing into his thighs and he was still pushing through! What the heck, Korean Citizen?!
