Hundreds of duck hunters in the Cache River area?

On a BirdForum thread, I found these two quotes about the Cache River Ivory-bill search area:
---
"Its amazing that this bird has lasted in that corridor because its filled with duck blinds where hundreds of duck hunters go each year."

"Winter is the time to go... but be aware from thanksgiving until about the end of January it is inundated with hundreds if not thousands of duck hunters. You will find duck hunters will return courtesy in kind.... IE don't head up the cache at 9AM and drive through everyones decoys...

We've spent years hunting waterfowl on the cache, and mostly in the areas where the Ivory-Billed has been spotted..."

Some people have the impression that no duck hunter knows about any other species, but that's simply not true. Some duck hunters are skilled birders, and they would recognize an Ivory-bill, given a good look. If you believe that there are Ivory-bills in Arkansas, you must not only believe that the birds have somehow avoided giving Cornell's team a good look. You must also believe that they've avoided all those camoflauge-clad hunters year after year, inundating the area for weeks when the trees are bare.

At this link, there is an announcement that waterfowl hunting will continue in the area this season. There's a new permit system in place that will allow a maximum of 76 people per day into the 7.5-square-mile "Managed Access Area".

Here are the duck hunting dates and bag limits. I think it's notable that Pintail duck hunting will be allowed in the area, even though Tanner said "In flight the Ivory-bill looks surprisingly like a Pintail".
