My name is James Pearson and we currently have a temp course that we set up every Sunday at 10:00 and Wed at 4:00 here in Daegu. You will want to contact Chaz and be added to the - Korean Professional Disc Golf Association - facebook page. That is the best way to find out about the disc golf in Korea.
My email is firstname.lastname@example.org. Let me know when you can make it down. I have lots of extra discs if you need to borrow any to play. Chat with you soon.
