For those who travel frequently in Korea, how is the air quality? Since Korea generates about half its power with coal burning, and prevailing winds carry pollution from coal-powered Chinese industry and electrical power generation across the Yellow Sea (along with fine grain sand particles from the deserts of western China), all of which result in terrible air quality in Korean cities. I've lived in China before, and I have no wish to breathe harmful particulate matter day after day like I did then. European cities aren't great for that either with the diesel engine emissions.
Perhaps air pollution is not as much as a concern in rural areas, but certain times of year I would imagine it is certainly an issue whether in a dense city or not since Korea is quite small. Are there particular times of year that are best for cycle traveling the country?
