Seems decoying is a never ending learning process.
First year we timed it perfect and hunted during a snow storm in ND...got like 100 in 2 afternoon hunts. Year after that took us a long time to find birds and again we were in ND in a major snow storm. Finally found them Friday evening and got one day of hunting in on Saturday...shot 70. The next year there was no water, ended up finding a small area holding birds and got like 40 in 3 days. Last year sucked as we hunted a corn field in SD with no open water right after a snow storm. There were a ton of birds but everything wanted water...only got like 20. No more straight fields for us MUST be a water/field combo.
Beginners luck? We've been sucking each successive year haha. It really is hard when you go for one four day weekend. Hoping this year to maybe go a couple times...see what happens.
We run about 800 sillosocks, flappers, 4 speaker caller, couple homemade vortex's, couple wheelers with aggressive tires. One of these years tracks will get added to my wheeler.
