Summer in Seoul was dreadful. It was hot and sticky and I was sweating nonstop. This made me not want to leave the haven of my apartment where I had the AC on all day. But alas, it was summer vacation and I had one week to try to do something. Emphasis on try because leaving my apartment was torture.
I managed to go Incheon for a day. The train ride is a little over an hour and you bet I found all the air vents in the subway stations while waiting for it to come. I had the misfortune of sitting between three older people who had horrible breath and were constantly talking to each other and I moved to different car to escape from them.
