Yup, that's the article. I find it a bit hard to believe that many farmers will invest the time & gas & manpower to use the suggested "chaining" procedure prior to harvesting their hay.
As far as your question on how my first Unit 1 hunt went, I loved the area. I'd likely be posting photos & bragging if I'd gotten turkeys, so I should man up when I get skunked. This is the first year in the last six that I didn't get at least one tom. A year like this one makes me wonder if I ever knew how to hunt turkeys in the past, or if they just happened to walk past me in spite of my calling.
In SW Wisconsin (near Gays Mills), 4th period, I twice saw strutters with hens in big fields ~ 2-3 shotguns away. They were content with the hens they had. Closest call was a gobbler that I never got to see over a ridge ... got him within ~75 yards, but never did see him. He responded for ~30 minutes before leaving. The woods ridges were incredibly bare of foliage for that time of spring ... I (& the gobblers) could see a long, long ways up & down those ridges. Much, much ridge climbing for me. My bum ankle wouldn't have lasted another day. Got pretty lucky with the weather that period. As a guy living in suburban Green Bay, I envy your living in that beautiful turkey rich area. Not just for the hunting season, but for the ability to easily get out & observe them year round.
Last two periods in my home zone 2 I only hunted for a few days each period due to other family things going on, but I hunted hard on those days. Weather (wind/rain/hail/fog) was a factor as it always is, but I got enough decent weather. Saw a lot of hens & I let quite a few jakes live for another season. I may not have been so generous if one of those jakes had shown up in the last hours of the last hunt day. Very rarely got a tom to answer calls, & never did call one close enough. Those toms that I was able to spot at a distance were in areas I couldn't go, & they had no interest in my calls. Had at least three cases where I would've/should've had a shot except for bad decisions, or I prefer to think bad luck.
Now my wife is even suggesting that I change our incoming email notice to something different from the loud tom gobble.
