Getting to Yong-In took quite a bit of time, but I wanted to watch some sparring, and I'd never been to Yongin city before. The campus was both compact but spacious feeling.
I think the large building you see is the martial arts building.
I texted TempMaster from the campus to tell him I was there. A few hours later he called me to ask how I was, what I was doing at Yong-In, and to invite me to the studio at any time. I picked up a Yong-In University Taekwondo t-shirt for him. I wanted to get him something in Hong Kong to thank him for allowing me to train at his studio temporarily, but I couldn't find anything. While I'm sure he has Yong-In t-shirts, I think he'll like it.
