I got permision to hunt a new farm this year. Saturday morning was spent watching many geese land on a flooded area of the field and ignore my setup on a high spot. Sunday I set up in the flooded spot. Took a limit of geese in 35 minutes and got out of there. It looks like this spot will hold water for a few weeks so it should produce constantly if I hunt it right.
As a side note, about 100 mallards appear to be using the same spot. Come on duck season.
