Ironically, in Wisconsin it's "concealed carry" that's illegal. You can "open carry" legally, although you might find youself in trouble anyway if some jerk cop thought you were brandishing in some way...
Open carry is legal there? Well, if it’s my only option... I hate that though, it’s just broadcasting it to the whole world “reach here if you want to try to turn my weapon on me,” not to mention possible (probable?) legal hassles from a jerk cop who needs to fill his quota of “disorderly conduct” citations.
