Hmmmmm. Think there may be some warden discretion involved in Wisconsin. A few years ago, I shot a turkey on private land during the Spring season. My brother was still hunting so I was planning to do some stump shooting and morel hunting in another part of the woods. About that time, a warden came by, checked my license, tagging of the turkey, etc.
I told him what I was planning to do and asked if he would have any problem with that. He said it would look like I was still turkey hunting to him and that he would probably cite me if he saw me doing it. Even with blunts only in my quiver and coyote season open? Yep. Needless to say, I hunted morels without my bow that afternoon.
I don't know if that view is universally held by all Wisconsin wardens, but it's something to think about. I do know that some wardens have never heard of stump shooting, have no idea what it is.
Would probably be vindicated in court, but that's a waste of time and money.
