Well, I got it solved. I asked Sa Bom Nim tonight, and had him write it out in Hangul. Since I'm in Korea, that is often the best way.
It is written 육로, which technically translated is Yuk Ro. BUT, if you are Korean, it is pronounced Yoong No. In addition the sounds for "o" and "a" are very close, because the letter for "a" is a long "a" sound. So it was Yuk Ro, but Americans have adapted the pronunciation from people who have learned basic hangul, but not the full pronunciations.
Thank you for your help!
