RE: Duck calls
I don't know how it is in the rest of the country, but in PA and NJ, the best duck call is no duck call, especially on public land. Let the decoys do the work. I've seen calling (bad and good) spook more birds than suck them in. One lake in particular, there would be 10 guys around the lake calling their heads off (and some sounded good.....to me), we'd just shut up and would ALWAYS outgun the other guys. They'd drop right in. You'd let out even the quietest feeding chuckle and ......SEE YA. Game over.
