Fished sun out of LE Inlet out about 5 miles. About a mile south of LE reef. Ocean was flat the whole time, no wind. Caught some fluke and the usual junk fish. Suddenly the boat became covered with black flies. No lie hundreds of flies. Biting our ankles. Tried moving around , chased a school of bunker for about 2 hrs. couldn't lose the flies. How do they get so far away from land?
