The girls & I drove up to Tongyeong to ride the Sky Car today but apparently it is closed until the 27th. So, on our way back toward home I kept seeing signs for the "Undersa Tunnel" and thought we'd give it a try. The amount of signs made it seem like an attraction (and the signs were brown like the other tourist attractions in Tongyeong). So, we found a place to park and walked through the dripping, moldy tunnel. It's just a walkway that happens to go under the water. I thought maybe there would be a window or something to see some water but it was just concrete. The girls didn't seem too disappointed but Sarah dropped her cat in the mud and it had to take a trip through the washer and dryer before I could give it back to her!
