20 years ago you could get free natives by touring a DNR hatchery. They even gave papers as proof that you received the fish from them so it wouldn't figure into your daily bag limit.
You might be surprised you could have one within a hours driving and never know. You could try seeing if one is near and if its possible to get a fish from them. I know they did it 20 years ago in Minnesota just not sure if they still do this or whether they do this in other states.
