For those of you that know the area, the racetrack is by Seoul Grand Park, AKA - the zoo. To get there by subway, take subway line 4 to Seoul Racecourse Park station, leave by exit 2 and follow the crowd down the covered walkway to the track. Races happen most Saturdays and Sundays from 10:30AM to 5:30PM. The entrance fee to the park is 1,000 won.
Just so you know, H1N1 is in full force here in Seoul, so it was no surprise to see these guys at the entrance.....
