Decoys are really helpful. I carry a jake and 2 hens. For effect, I re-painted my jake to look more realistic - I added more color to his head, and painted him really glossy black.

Be careful using them, b/c I had a guy blow my jake off the pole one day. It was a pretty scary situation. Luckily, he came in from my side, and I wasn't in the line of fire. I think the jake is more effective than the hens.
