In the area of the country I hunt, there are many winter wheat fields.
I don't have much experience with laydown blinds, but from I've seen, I'd think a laydown would be a hard sell in any part of the field until the snow comes, and they can be covered with white.
Now I'm hearing that the birds are getting pretty savy about the laydowns earlier in the season each year because they are getting shot at by every one they see, and they pick 'em out real quick.
I wonder if mixing some of the old G&H 747s in the set, and dressing in the same colors in a fetal position in the spread, wouldn't buy you a few more close in shots where the birds have gotten laydown wary?
May not be quite so comfortable, but being just one more big brown/gray lump in the set of big brown/gray lumps might work?
