I just went and looked at the count. Of the 238,000, approximately 93,000 are at Chautauqua Refuge. Now, if you figure they are flying approximately 60 river miles on the lower Illinois section, that amounts to less than 4,000 ducks per mile. If we subtract those 93,000 on the refuge, there are slightly more than 2400/mile. I'd venture to say that a good portion of the 2400 ducks in a mile could become very invisible to the average guy doing a little windshield scouting.
Besides, on all the forums I frequent, in general I'm hearing fair to good reports in regards to the Central Zone opening weekend.
