Had I know this person a month earlier, I could have cancelled my Busan stay and bought a KTX ticket , hop on the train to Seoul instead! May be on the way back drop by Daegu to visit another new friend there, if you know who am I referring to, a must visit and well respected person in my opinion! Now that I need to plan my 2nd South Korea visit! Good job there and looking forward to crash into your discussion more often!
