I've been living in Aurora, Indiana, just downstream from the mouth of Hogan's Creek, with a view of the river. Lo and behold this morning I caught a glimpse of a commercial fisherman at work. I've been keeping an eye out since last week when I saw some strange marker buoys in the river just offshore. He came all the way from Missouri, 400 miles away or so. Missouri tags on his pickup anyway. I'm not familiar with net setups, but there is clearly a line running from the Indiana shore to one of the marker buoys. It's not especially heavy.
