I actually just returned to Canada a couple of months ago after leaving Korea. I started riding in Korea and did a few Ulsan to Seoul trips (among tons of weekend trips around Gyeongsang, basically Pohang at the north to Geoje at the south).
Man, riding in Canada is nowhere near as fun as Korea. So many brilliant twisty roads all over the country. It takes a couple of hours to get to the twisties from Toronto (there are a few twisty roads in Toronto but they're quite short and sparse).
