Ryan gave you good advice..

There are ways of attracting huge numbers of waterfowl,, most arent legal so I wont give you any suggestions on how.

The best blind,, is good camo(including a face mask)stay absolutely still when birds are in the air.

3" #2's and buy GOOD steelshot loads,, speed kills with steel.. I personally like 1560fps Fasteel.

The suggestion for calls, buy one and put it away.. learn too use it for next year,, if you were hunting with my group of buddiesand you pulled out a call with very little practice with it.. youdbe given2 options,, put it away and not take it out again, or go swimming for it!

If you guys have no one with experience calling ducks,, dont call them.. It will be a bigger detriment to you than calling and not knowing what you are doing.
