That video isn't bad, but I have greater interest in your cycling videos. Last summer I rented a road bike when staying at the IC CoEx, and rode for a couple of days along the trails. I was very impressed with the quality of the cycling infrastructure, based on what I saw in the 100+ km that I rode. Mainly I was on the trail along Tancheon and the south bank of the Han River, as far west as Bangwha Bridge.
