are they possibly referring to hunting freshly planted winter wheat fields that haven't germinated yet? and herbie, I guess theoretically they could write you a ticket for that(they CAN write one for almost anything), but if it got serious it would not hold up if you fought it very hard.
My brother in law ran into a guy early last week while scouting some public land north of Winnie and the property was a rice field in years past. The guy was telling him the GW's would write tickets to people and dog owners if they weren't going straight up a row. So apparently knocking down rice while retrieving is baiting as well, then also I can see that is also lost crop to the owner. However, the farmer is taking a chance on that happening since the rice is still in the field not yet harvested. It's somewhat of a gray area to me and yeah I could see stuff like that being thrown out if fought.
