In the center-left of the photo above is a building with a South-Korean flag on one side and a U.S. flag on the other. It is the "Korea Christian International School" (한국기독국제학교), which I'd never heard of till now. The existence of such a school is testament to the strength of Christianity in Ilsan, and in South-Korea generally. Actually, it's hard for me to imagine a "Korea Buddhist International School" in Ilsan. If there were one, it wouldn't be so conspicuous or "self-confident", I'd imagine. Buddhism is so lethargic/undynamic in Ilsan as to be near invisible, in my experience.
Here's a (3D model) view from near the same spot, but looking west. You can see a lot of small single-family homes.
Lee H.J. (who was in 6th and 7th grade when I taught her in 2009-2010) provided me with a memorable line I've pondered ever since. She wrote, "Today is only tomorrow's yesterday." She wrote it in an essay. What does it mean? It seems like it could/should have some deep meaning, but when I try to grab onto that meaning, it always conceptually slips through my fingers, like trying to grab onto a cloud.
