freezing temps

for the guys new to pit hunting, just a heads up. What usually happens after a hard freeze is good hunting as ducks are hungry to get back into the fields when they thaw and look for ducks in places that they haven't been using. Ie slash water and the corn field. Break up the ice the night before and sometimes our best hunts take place. The question is how long will it take to thaw. Watch the weather and good luck.
