Below you will find a link to an article in MidCurrent writen by James Card on fly fishing around the DMZ. His description of land mines getting washed down strewam durring high rain times beings the concept of a difficult wade to a new level. I have also linked James Card's website. I guess this goes to show that ytou can find fly fisherman anywhere.
