This sign is located in Monument Park, and has Korean (Hangul) written on it.
You cannot link with this because it is out of the reach of the player.
The sign reads: "컷읏텃긋컷읏텃긋혓벗돗섯혓벗돗섯". The writing does not mean anything specific or meaningful in Korean; it is a disarray of gibberish intended as a tongue twister.
The pronunciation in English is "KEOT EUT TEOT GEUT KEOT EUT TEOT GEUT HYEOT BEOT DOT SEOT HYEOT BEOT DOT SEOT"
Maybe it is '컷웃텃굿(KEOT UT TEOT GUT)', not '컷읏텃긋(KEOT EUT TEOT GEUT)'.
When you say them out loud, they sound like this is English;
"컷읏텃긋" can read "Cut out that gut"
"혓벗돗섯" can read "hurt but don't soot"
It is not known if this has any meaning or context, but it may be some sort of Easter Egg.
