If the ducks aren't there, won't matter what blind you pick.... they will all suck.
Any of those blinds are better than none.....
It's been a long while since I hunted a blind in the bottoms.... almost not worth the hassle.... all the overgrown kids and disrespectful people that think they have more right than you to be there.... fight's at the boat ramps.... cussing & carrying on.
In Unit #2:
Back in the day.... the "triangle field" (#124, #125, & #128) was pretty good, especially if you have good neighbors.... blind #128 was the best of those 3 blinds last time I hunted there (1994).
If you want to get out away from the crowd so to speak, the "field" blinds, #72, #73, #74, & #76 aren't too bad... I also hunted in #76 several years ago....
In Unit #1:
If you want the corn draw, the blind along the highway are popular... #106, #107, #108, #136, #140..... If you get a blind along the tracks, you will have to deal with the trains passing by often.... but any of the blinds in unit 1 will hear the trains.
Things may have changed quite a bit since last hunting there as far as which are the better blinds.... But I am sure the disputes, skybusters, disrespect, and thieving still goes on.
