Here is how I did it.
Carry as little as possible, just a half dozen dekes. Bring enough to drink, and be ready to move if possible and can do so without disturbing other hunters. Carry your GPS if you have it, and start a spreadsheet with conditions such as wind and temp, what sort of ducks you saw, etc.
Next time out do the same thing somewhere else, and keep going until you find some spots. Conditions change every year, and while one pond may be the hotspot the previous year, the next it may be a different one, and not the spot where everyone and their brother goes (cough, cough, Hourglass, cough cough).
